Steves Muffler Service

I took my car to get my muffler welded because it had broke I found out it had a warranty through *** so when it broke a 2nd time I took it to *** to find out that the part they replaced had been removed so I return to steves muffler shop to collect my piece that he cut off only for him to tell me that he has never seen me or my car before and upon looking at the reviews on google come to find out im not the first person this has happened to.
