Busy B Muffler Brake

I took my audi over for a muffler that went bad. So as they say replace one do the other as a dealer would say. I got two end mufflers for it their Aluminum/stainless, so they would last longer. I only noticed one rotted. So I waited and he started cutting it apart and says the middle was bad too and he took it off. I said I'll keep it because it didn't think it looked badat all. So I left it to the professionals, and I specified that it has to WV pass inspection knowing he work in Weirton, WV. He said yes it would and he would call weirton because they were busy. I paid them cash for the job. So this car has two mufflers on it now. I went to get an inspection done on it and they were booked. At inspection time it get better these weren't mufflers they were resonators. Now I'm not the professional here. I couldn't get it inspected from their company's job. I called and said this won't pass the inspection. He said bring over so he could look at. I brought it over and they told me the same price to have it done again. I said you already been paid and he went in back with someone. It will cost the same price, and that's cheap, I said wait a minute you want me to pay for the job that was done here twice because you messed it up. His buddy was helping him out. So I said ill stop back as I was ready to get mean. I call him back nicely and said you would take care of it fro me because your were the professional here. Bring it over, I said I did that last time. I don't know what vehicle it was, this was within a week. We get a hundred cars in a day (in a two car stall) taken 3 hours out of 8 hour day to mess mine up. So my time, frustrations and money was wasted.
