Supa Quick, terrible service

A year and a half ago, Supa Quick replaced my brake discs and brake pads after I found my car to have a vibration on the steering when I apply brakes. They had me buy the discs and pads next door at AutoZone. When I went back, because the car was still vibrating, I was told that the lower control arms are shot. This was said after they pushed a piece of square tubing between the control arms and jiggle the tube. By then, I had enough and took my car to my mechanic. My mechanic sent me a video clip to show how bad the discs were. It had blue spots all over (proof of inadequate steel on the discs, which are brand new). I had to replace the discs and pads and took the faulty stock back to Supa Quick. I was told that it will be sent back to the supplier, be tested and they will contact me. I am still waiting. They owe me a lot of money. I had the lower control arms checked at my mechanic and even when I was in Cape Town and there is nothing wrong with them. I am still driving with the discs and pads my own mechanic replaced their faulty stock with, and no problem. Stay away from Supa Quick and AutoZone in Montana!
