Where can I look to find the legal rules and regulations pertaining to customer service of a professional business? The reason I ask because, I recently had my car painted, and the manager/owner did not have any customer service skills, he was actually nasty. I did file a complaint with the BBB and in doing so, I found out that this company has an unsatisfactory record with BBB due to two other complaints with no reply, which means, the company apparently ignore the complaints and continue to be nasty. Does a company have a legal obligation to treat customers with business etiquette?
