I set up an appointment online to have a 150,000 mile service done for $167.99 as well as a 4 wheel alignment for another $70.00.... I received a confirmation call to confirm my appointment time and everything i wanted done. When i arrived the guy i spoke with had no clue why i was there so we had to ring it up and then told me that the alignment $80 and that it was only for the front wheels. I had to pull up the website on my phone to prove i wasn't lying. I got everything for the right price but then i get a phone call telling me the service tech cross threaded 2 of my wheel studs and that it would be an additional $110.00 to fix it. I asked why i had to pay to fix something they broke and i was told that the tech didn't do it because he was standing there when it happened so it must have been done by the previous person who worked on it. When i told him that i was the last on to take those wheels off and that i used a 4way tire iron he pretty much called me a liar, but not directly. I feel like they tried to take advantage of me. But needless to say i left with 2 wheels on my car missing a lugnut. Both the front and rear passenger side wheels are currently being held on by only 4 lugnuts instead of 5
