F.A.S. Muffler and Tires

Brought in my [redacted] to get a pair of tail pipes built, already had purchased the x pipe and mufflers from [redacted]. I was first quoted $150 for the job by Franks technician and then when Frank (the owner) finally showed up to his shop 2 hours later he gave me a quote of $200 for the job.
Showed up the next morning with the car. Said that I would have to wait until 4 PM. Frank proceeded to leave the garage and have his technician handle the job. A couple hours had gone by and all that had been done to my car were the mufflers welded into my pipes. This was the first issue that I had with them, as before they started the job I had asked that exhaust clamps be used so if I decided to change out the mufflers at any point I wouldn't have to cut them off.
Didn't really make it to big of an issue as I have the tools at home to take them off if needed later on. Franks technician proceeded to try and bend the pipes to make the tail pipes and went through about 6 or 7 bars of 6 ft. 2 1/2 inch exhaust pipes trying to make the right angles.
During this time a few other customers had come in to get an inspection and were unable to get it done because Frank is the only one with an inspection license. His technician was very rude to them and told them basically to get lost. During this time managed he also managed to cut and gouge my new mufflers and cut about 3 inches of my new chrome exhaust tips.
After I checked my watch it was about 2PM and I was heated because nothing had really been done and his technician was clearly under qualified for the task at hand. He proceeded to call Frank and I was told that I can either leave the car there or pay for what had been done so far. I asked them to drop my car of the lift and I will take my business elsewhere.
The owner clearly does not manage his business like he should and I would warn anyone from ever going here to get any exhaust work done, or any work done just because of their attitude. Very rude and Unprofessional
