I, also, do not believe that the BBB will be able to help you at all. When I first started in business I received several complaints with the BBB and tried my best to resolve all of them. Nevertheless, people who called the BBB to check out my company before dealing with me got very negative information.
One day the BBB sent my company an application to join. We wrote them a check and joined and never received another complaint in the next 30 years and always got very positive recommendations from them. All we had to do was keep our dues paid up.
The Attorney General's office usually has a consumer affairs division that may be able to help you.
