I had a slow leak in a tire. Used some Fix a Flat. Several days later I took my car to Pep Boys to have the leak repaired. Pep Boys tells me that they cannot repair the tire because the acid in the Fix a Flat has damaged the inside of the tire. I contacted the owner of Fix a Flat and they sent me the MSDS sheet which shows there is NOT any acid in their product. I asked Pep Boys to remount the tire and they said no because it would hazardous because the acid has weakened the tire. I had warranty on the tire. Pep Boys ordered a new tire, but I had to pay $72.07. I had the tire mounted. A couple of hours later the service writer at Pep Boys called me and said the reason they would not mount the old tire is because I rode on the bead. The tire never got low enough for that to happen. First Pep Boys tells me one story and then they say something else.
What I would like to happen is have a refund of $72.07 and never deal with them again.
