I called the on a Friday to see if they could change the timing belt on my car, they said to bring it in early the next day. I even asked them if having the right belt for my car was a consideration and they said it was fine. So I took my car in at 7 am the next day, and spent over an hour getting home by bus. Since I needed new tires too, I also asked them to rotate the front tires to the back and give me new front tires. Later that day, at 4 pm, I get a call from them saying that they took my car apart and then noticed that they didn't have the right belt. They tried to get me to leave my car until Monday night, but I told them no because I had to go to work. When I got there to see my car, I saw that they just put the new tires on the back. When I mentioned it, they said they couldn't get the tire off. But by that time I was just feeling lucky to get my car back in one piece, so I took it.
It's pretty obvious that they lied about both. There's no way to put the timing belt back together in 2 hours, so it's obvious that they were just trying to get me to leave it until Monday. Also, if they had tried to remove the front tires, the gun would have broken any of the nuts off if they were stuck.
