Service Street Auto Repair - Thornton

I brought my car in because it was hesitating and had a check engine light on. After 1 day I was told that it was a air intake hose had a crack in it. Well about $500.00 later I got my car back (after they had charged someone else's credit card for my bill by mistake) and low and behold the belt was squealing (which it was not doing that before) and the problem was still not fixed. I took it back to them and they informed me that as far as my belt I would have to replace it myself even though it was not making a sound until Service Street mechanics touched it and that my actual problem in my car was a catalytic converter. I was told that my cat could not be replaced with a universal catalytic converter and it had to be the highest priced part from the dealer and that they could have the part there the next day. I called multiple dealerships and the price of that part was 50% less than the quote from Service Street and that it would take these dealerships 2-3 days to get the part in. All in all Service Street told me that in order to replace my cat it would have to be another $1,500.00 with $900.00 of that being the price of the catalytic converter. I thought that was absurd and have taken my car to actual exhaust shops and each of them quoted me $250.00-$300.00 for the total service including the UNIVERSAL catalytic converter. THIS SHOP IS A SCAM!!!!!!! YOU RIP PEOPLE OFF OF THEIR HARD EARNED MONEY BECAUSE YOU ALL ARE TO LAZY TO WORK HARD FOR YOURS!!!! I know a lot of people in the Thornton area and have told them how exactly this shop conducts business.
