Service Provided

i went to clays and was completely unsatisfied. they charged me 400$ for a problem that they werent even able to fix. not only that, but they did something to give me a terrible oil leak so that i would have to give them even more money. before going through with it, i got a friend who works on cars to take a look at it. he said that all it needed was to be tightened. i cannot believe someone would be so untrustworthy with a car that they would do something like this to get more money out of people. worst service ever i will never be going back.
