Dissapointing Experience

Purchased a new CLA in Nov 13 and had to do a service after 1yr, after the service my car was returned with scrathes and dents, had to speak to DP to get this resolved eventually only to get the car back with a bad sound on my left wheel, went back in and they repaired the wrong part making the car worse, they then took the car back and resolved the problem on the front left wheel but i got 1 extra scratch.). 3 weeks after, brakes went without warning and had to drive in urgently the same time, they sorted the brakes in the same day but yet again got another scratch. a week later and now the sound on my front wheel is back and makes me worried every time i drive the car. Tired of gonig into the branch to constantly have my car checked and fixed and getting scratches and dents on my car. i should have rather stayed with my Toyota which never dissapointed me than go to the so called \premier brand"and have this much headaches"
