You are a lot more patient than I. At the point of call number 3 I would of filed the complaint and asked for a $$ for repairs. At this point I would just contact BBB. Good luck. Oh, just ask Hellmutt how patient I am with contractors . We had a company fix our leaky basement, they took 5k off the price to start. I actually called and complained the first day they were on the job, they were on point after that. I have little woman syndrome, therefore I am loud.
