About this business

Based on the records I reviewed, A&J Auto Body Mobile Repair and Jimmy Mark Demetro appear to operate out of Hayward, Alameda County, California. The number used in the business’s public advertisement and in my communications with the provider appears to be a business line: +1 (510) 789-3694. It is published here only because it is the number the business itself advertised publicly, and because other consumers may recognize it. Please do not call or text it — take your complaint to the agencies below instead.

If you file a complaint, provide the full business name, the location, dates, amounts, and any phone number or advertisement you used directly to the agency. Agencies can verify registration and contact information through their own channels; you do not need to contact the provider yourself.
