Go to your GM again, and request the Regional Manager and Corporate HRs phone numbers and emails. The GM has proven that they are incapable of talking to this manager about the issue you need to go to their boss. If they refuse to give you this contact information(which by Federal law they cannot) then you need to contact the Better Business Bureau in your state. You also have the right, at that point, to talk to a lawyer about it, and they could inform you of whom to contact, or whom to issue a Cease and Desist to.
