File a Complaint

Thank you for contacting the Minnesota Department of Commerce. We appreciate your willingness to bring this matter to our attention and your patience during the investigation.

How do I file a complaint?

The quickest and most efficient way to file a complaint is through our online portal. If you file using the online portal, you will be able to see the status of your complaint,  communicate with the investigator, and add documents throughout the investigation.  You will need to have an email address to file your complaint on the portal.

You can also file a complaint by email at consumer.protection@state.mn.us or by phone at 651-539-1600 or 800-657-3602.

How do I submit more documents or comment on my existing complaint?

Sign into the complaint portal using your email address and password, go to the complaint submission history at the bottom of the page, find your complaint and click on the Comments/Documents under the action tab.

What complaints can Commerce investigate?

Commerce regulates over 25 different industries.  For most of these industries, we can investigate complaints from consumers.  However, some areas are outside of our jurisdiction.  If that is the case, we will try to direct you to a more proper place to file your complaint.  In other cases, a court of law may be a better venue to resolve your complaint.  

Do you accept documents that support your complaint?  

Providing documents, emails, or photos to support your complaint  will help us in our review of your complaint.

We can accept files that are in Microsoft Word, Microsoft Excel or PDF form. For any document that is not already digital, you can take a photo with a smartphone and submit that as a JPEG file. If you have an email from the business, you can save it as a PDF and submit that with your complaint.
