Business Complaints

The Consumer Protection Division helps Maryland consumers resolve disputes with businesses through mediation. We can assist if you're a Maryland consumer with a business dispute, or if you live elsewhere but have a dispute involving a transaction that occurred in Maryland.

Note: All complaints submitted become public records subject to disclosure requests under state law.​ However, confidential information (financial, medical, or psychological) remains protected.
