Many people are unaware of mechanisms to address consumer complaints in Thailand, and particularly concerning the existence and role of the Office of the Consumer Protection Board (OCPB).
The OCPB receives complaints from consumers who suffer hardship or injury resulting from the acts of the business operator for submitting it to the Consumer Protection Board for further consideration and proceeding. Every consumer being disadvantaged or injury from any product or service can make the complaint at the Office of the Consumer Protection Board, the Government House, Bangkok 10300 by sending letter to P.O. Box 99, Bangkok 10300 or coming by himself/herself or by telephone hotline number 1166. There is also an online complaint lodgement facility.
Consumer rights are addressed in The Consumer Protection Act B.E. 2522 as amended by the Consumer Protection Act (No.2) B.E. 2541, details of which are summarized here.
