utterly bad service

My car a black Hyundai Getz 2004 1.3, was scratched allaround by school children in 2012, my insurance company at that time send my car for a re-spray to Euro Panel Beaters. Since the firts time my car went in my carwas never repaired properly and i was never satisfied, the paint never matched, the paint would crack after n couple of months, my door strips was broken off and clued back on the body and fall off every couple of weeks, central locking was broken, electrical windows was broken, wires inside the car for the radio was messed up, the car is over polished and burned with the buffer the doors an bumpers are not aligned there are vinger nail prints in the paint the car was once filled withmildew. The car was Desember 2014 there for the 6th time for yet another re-spray and repairs and has to go back again because still the paint is cracking my doors en bumper is not aligned and my strips keep falling off. In total since 2012 the car was at there workshop for over six months. I will not be able to sell the car ever due to the horrible condition the car is in because of these guys. I am frustrated because this has been going on since 2012 and yet the car is still cracking up!
