Disgusted with service

I am very disappointed, in today times its extremely difficult to find a trustworthy mechanic to work on your car without taking shortcuts, i have found myself such a mechanic, Charl and his team at CNR Automotive, after asking the sales person on the phone when going through the contract, i asked if it will be a problem my mechanic and was told no, if its not on the list, you just sign a waiver that you will not hold anyone liable for bad workmanship, when my car broke down now, i am told sorry, they cant help me, i should have taken it to one off the dealers on the list. now i had to pay for the parts and workmanship out of my pocket. if i had known that, i would have not taken this policy at all.
