Centurion Car Care

I had some work done to my car a little over a month ago. After getting it serviced the problem was still occurring. When I took it back to the shop I was told that the current problem I was having was caused by something else. So I decided to get a diagnose test done by another mechanic shop, and they said the problem I was having was being caused by the same problem Centurion had supposed to had fixed and to take it back and have them correct it. So after taking it back to Centurion again for a 3rd time they wanted to charge me $200 labor to take another look at it plus money for any additional parts needed. Are there any good truth-worthy mechanic shop any more.
