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.

Before You File

  • The Consumer Protection Division mediates most complaints about goods, services, or credit obtained for personal, household, family, or agricultural purposes
  • Health care or medical billing disputes are handled separately: File a healthcare complaint
  • Complaints about federal executive orders or Department of Government Efficiency (DOGE) actions: Use our General Office Contact Form
  • Business vs. business complaints: We cannot mediate disputes between businesses unless the filing business is a nonprofit organization
  • We cannot mediate anonymous complaints​​​

What Happens Next​​

Complaint Review & Assessment

  1. Initial Review: We assess whether our office is the appropriate agency to handle your complaint and may request additional documentation and/or information.
  2. Assignment: If appropriate for our mediation, your complaint will be assigned to the next available mediator.
  3. Business Notification: Unless you specify it's for informational purposes only, the business will receive a copy of your complaint. We act as an impartial mediator between you and the business to find a fair solution.​
  4. Mediation Process: ​A mediator will work with both parties through phone calls and written correspondence to reach a resolution.

Mediation Timeline​

Resolution time varies based on case complexity and the responsiveness of the businesses involved. Simple billing issues may be resolved quickly, while complex issues may take longer.

Complaints are handled in the order received and assignment times depend on current caseload or filing deadlines.

If Mediation Is Unsuccessful

Please understand that we cannot force a business to cooperate with our mediation efforts, and we are not authorized to provide legal advice or serve as private attorneys on individual cases.
