Wisconsin’s main consumer protection agency is the Department of Agriculture, Trade and Consumer Protection (DATCP), which processes more than 100,000 complaints and inquiries a year and returns millions of dollars to consumers through its Bureau of Consumer Protection.1Wisconsin Department of Agriculture, Trade and Consumer Protection. Bureau of Consumer Protection You can reach the Consumer Protection Hotline at (800) 422-7128 or DATCPHotline@wisconsin.gov, Monday through Friday from 7:45 a.m. to 4:30 p.m.2Wisconsin Department of Agriculture, Trade and Consumer Protection.

What DATCP Can and Cannot Do
DATCP investigates deceptive business practices, enforces telemarketing and do-not-call rules, regulates residential rental practices, and helps identity theft victims. When you file a complaint, a Consumer Protection specialist contacts the business on your behalf and tries to broker a voluntary resolution.
The agency acts as a neutral intermediary. It cannot force a business to pay you, award damages, or act as your lawyer, and it does not give legal advice.3Wisconsin Department of Justice. Protecting Consumers Its leverage comes from the record it builds and from referrals: the Department of Justice’s Consumer Protection and Antitrust team litigates cases that DATCP and other state agencies send over.4Wisconsin Department of Justice. Consumer Protection Concerns A lot of businesses settle at the specialist’s first contact for exactly that reason.
How to File a Complaint With DATCP
Pull Your Documentation Together First
Before you file, gather the business name and address, the dollar amount in dispute including taxes and fees, and copies of anything in writing: signed contracts, dated receipts, warranties, advertisements, and emails or letters between you and the business. Put them in date order so a reviewer can follow the sequence without piecing it together.
Note the dates you spoke to the business, the names of anyone you dealt with, and what they told you. Specifics move the process; vague complaints stall.
Submit Online or by Mail
The online complaint form on DATCP’s website lets you upload scanned documents directly.5Wisconsin Department of Agriculture, Trade and Consumer Protection.

What Happens After You File
A specialist typically contacts you within about a week of receiving your complaint.8Wisconsin Department of Agriculture, Trade and Consumer Protection. Information on Filing a Consumer Complaint They then present your complaint to the business and give it a chance to respond or propose a resolution.6Wisconsin Department of Agriculture, Trade and Consumer Protection. General Consumer Complaint If the business cooperates, you may reach a refund, repair, or other fix without going further. If it refuses or ignores the agency, your complaint stays on record and can feed into a broader enforcement action.
The Laws Behind Your Complaint
Most of DATCP’s authority comes from Wisconsin Statutes Chapter 100, which covers marketing and trade practices. Section 100.18 bars any advertisement, announcement, or statement made to sell a product, service, or property that contains untrue, deceptive, or misleading claims.9Wisconsin State Legislature. Wisconsin Statutes 100.18 – Fraudulent Representations Section 100.20 goes further, requiring that all methods of competition and trade practices “shall be fair” and letting DATCP issue orders against specific businesses or entire industries that behave unfairly.10Wisconsin State Legislature. Wisconsin Statutes 100.20
Businesses that violate Section 100.18 face civil forfeitures of $50 to $200 per violation, with each false ad or deceptive claim counting separately. Violating a court injunction that already told the business to stop raises the range to $100 to $10,000 per violation, and courts add a 25 percent consumer protection surcharge on top. Intentional violations of a DATCP order can bring criminal fines of $25 to $5,000 and up to a year in county jail.11Wisconsin State Legislature. Wisconsin Statutes 100.26 – Penalties A supplemental forfeiture of up to $10,000 applies when the victim is at least 62 or has a disability that substantially limits a major life activity, and courts must prioritize restitution to those victims before collecting any forfeitures.12Wisconsin State Legislature. Wisconsin Statutes 100.264
Residential rental problems fall under Wisconsin Administrative Code ATCP 134, which sets rules on security deposits, required disclosures, and lease clauses landlords cannot legally include. A rental agreement with certain prohibited clauses is automatically void.13Wisconsin State Legislature. Chapter ATCP 134 – Residential Rental Practices DATCP also runs Wisconsin’s Do Not Call registry, which currently covers more than 4.97 million numbers; a telemarketer who calls you after you’ve told them to stop is violating state law, and you can report the call to the Bureau of Consumer Protection.14Wisconsin Department of Agriculture, Trade and Consumer Protection.

When Your Complaint Belongs With a Different Agency
DATCP handles most consumer disputes, but several industries have their own regulators. Sending your complaint to the right place saves weeks.
Insurance
Health, life, property, and casualty insurance complaints go to the Office of the Commissioner of Insurance (OCI). Try the company directly first. If that fails, file with OCI online or at (800) 236-8517. OCI forwards your complaint to the insurer, which must respond within 20 days plus mailing time, and reviews the response against Wisconsin law and your policy. OCI cannot force a payout when the company followed both.15Wisconsin Office of the Commissioner of Insurance. Filing an Insurance Complaint
Banks and Mortgage Lenders
State-chartered banks and mortgage lenders fall under the Department of Financial Institutions (DFI). The DFI Mortgage Banking Section investigates alleged violations of state and some federal lending laws, and you can file electronically, by email to consumeract@dfi.wisconsin.gov, or by mail. DFI, like DATCP, cannot give legal advice, act as your attorney, or seek punitive damages for you.16Wisconsin Department of Financial Institutions. File a Mortgage Banking Complaint
Investment and Securities Fraud
Suspected investment scams, especially those aimed at seniors, go to the DFI Division of Securities at (608) 266-2139 or DFISecurities@dfi.wisconsin.gov. The division can also verify whether an investment or salesperson is properly registered.17Wisconsin Department of Financial Institutions. Avoiding Fraud Against Seniors
Vehicle Dealers
Complaints about licensed vehicle dealers go to the Wisconsin Department of Transportation, not DATCP. Give the dealer a chance to fix the issue first. WisDOT can address title problems, warranty repair disputes, undisclosed defects, odometer tampering, and unlicensed dealers, and an investigator typically responds within seven business days of an online filing. WisDOT generally cannot help with problems that didn’t exist at purchase, vehicles bought from private sellers or out-of-state dealers, or complaints filed long after the sale.18Wisconsin Department of Transportation. File a Complaint Against a Dealer Wisconsin’s Lemon Law offers a separate remedy against manufacturers for new-vehicle warranty defects.19Wisconsin State Legislature. Wisconsin Statutes 218.0171 – Motor Vehicle Lemon Law
When to Sue Instead
You don’t have to wait for DATCP. Under Section 100.18, anyone who suffers financial loss from a fraudulent representation can sue directly and recover the full loss plus court costs and reasonable attorney fees. If the business harmed you while violating a court injunction, the recovery doubles. The deadline is three years from the date of the deceptive act.9Wisconsin State Legislature. Wisconsin Statutes 100.18 – Fraudulent Representations
Small claims court is the practical venue for most consumer disputes. Wisconsin allows claims up to $10,000 for most money disputes and up to $5,000 for personal injury or other tort claims.20Wisconsin State Legislature. Wisconsin Statutes Chapter 799 – Small Claims Procedure The filing fee is $94.50, which covers the filing fee and the required surcharges; electronic filing adds a $35 surcharge per case per party.21Wisconsin Court System. Wisconsin Circuit Court Fee, Forfeiture, Fine and Surcharge Tables For general contract disputes, you have six years from when the debt became due or the last payment was made.22Wisconsin State Legislature. Wisconsin Statutes 893.43 – Limitation of Actions on Contracts
Filing with DATCP and preparing a lawsuit aren’t mutually exclusive. The agency’s complaint file, and the business’s response or silence, can become useful evidence if the dispute ends up in front of a judge.
