Bad service

I bought a car at chery alberton and I realized the is a cover with my auto care. I booked my car to remove a dent. They booked my car in with C K brothers, saying they are chery approved, my worsed nightmare, now my car has 2 colors, the paint they use doesn't match my care,I have sent several emails and no 1 is willing help. My car is ****ed up. On the other hand I booked the vehicle in with chery regarding the sound I get when I drive on high speed from the right back wheel but they never solved the problem. I so regret buying this car. My worsed decision ever
