I encourage you to file a formal DOT complaint, with service on AA's counsel. This offers many benefits: You get to see AA's response (which otherwise might just go to DOT, which may not share it with you); AA must respond publicly and on-the-record, assisting others similarly situated. DOT's web site makes it much easier to file an informal complaint. I'd be happy to help you file a formal complaint if you like -- just send an email or PM.
