File a Consumer Complaint​

Please use the links to the left to submit your complaint online.

For health billing and health insurance complaints, click on Health Care Complaint to the left and then select Online and Print Options.

Our staff is aware that our online complaint filing system encounters periods of time when it can't be accessed. We are working hard to identify and correct those issues. We know it is inconvenient and sincerely appreciate your patience as we work to take corrective action.

Please try to submit your complaint on the website first. If you have any problems, please use the below alternative options.

You may request a complaint form be emailed to you by emailing us at mediator@oag.state.md.us for complaints against businesses or heau@oag.state.md.us for health billing and health insurance complaints.

You may also download general consumer complaint forms here or health billing and health insurance complaint forms here.  ​

If you are a Maryland consumer and have a dispute with a business, or if you live in another state and your dispute involves a transaction that occurred in Maryland, you can file a complaint with the Consumer Protection Division. Through mediation, we will work with you and the business in an effort to reach a mutually agreed-upon resolution to the dispute.

Does your complaint relate to a health care or medical billing dispute? If so, click here to file a health care complaint. 

Please note that this office cannot mediate complaints filed by one business against another business.

Note: Complaints submitted to our office become matters of public record. Under state law, public records are subject to public information disclosure requests. However, all or part of the complaint may remain confidential as required or permitted by Maryland's public records law. For example, confidential financial information, and medical or psychological information about an individual will not be disclosed to the public.

Instructions to File a Complaint Online

1. Gather any documents that are relevant to your complaint, such as receipts, contracts, leases, repair orders or sales agreements. You may need to refer to these documents while you are filling out the complaint form and will need to send copies of these documents to our office after you file your complaint (see Step 5)

2. Choose the complaint form from the column at the left that best suits your complaint and complete the form online. (Some browsers may pop up a security error when you select a complaint form. You can click the enable button to proceed filing your complaint online or file a paper-based complaint instead​.)​

3. When you have completed the form, review the information you have entered for accuracy and then click on the "Submit" button. Your complaint will be sent to our office and you will immediately receive a "Complaint Confirmation" on your screen which contains the information you provided along with other important information about how we will handle your complaint. You will not receive an email confirmation.

4. Print the “Complaint Confirmation” page to keep for your records.

5. If you have documents that are relevant to your complaint, mail a copy of those documents along with a copy of the “Complaint Confirmation” page to our office. The address is listed at the bottom of the confirmation page. Please do not send original documents. You can also email your supporting documents to mediator@oag.state.md.us. Please include your reference number in the subject line.​

When we receive a copy of your documents and confirmation page we will proceed with processing your complaint. Read the links below for more information about what to expect once we receive your request.
