Cartime (Blackheath) worst nightmare

Cartime (Blackheath) is the worst. I understand someone may have a different view then mine but for me personally, it's been the worst experience in my whole life. I sent my vehicle (Mercedes Benz A200d) two months ago and my car is still there today. They've tried returning it 3 times assuring me it has passed all QC checks and test but I had to give it back coz it started exhibiting issues it didn't have before and two months later they're still trying to "fix it". I've never been this stressed in my life!!! All I wanted was a major service for my car and replace auxi****y battery, that's all I ever wanted and now I'm car-less!!!
