Diagnostic Repairs and Service Centre

got the most horrible service from Diagnostic Repairs. I've sent my vehicle to them for repairs and it's been 4 months and every time I get it back there's still something that is either not working properly or the engine is making a weird noise. My clutch was never working properly and the guy constantly has excuses about everything. I spent R 70 700 and my vehicle is still not repaired. I won't advise nor refer anyone to Diagnostic Repairs. The service that I have been receiving is absolutely terrible and the work that was done on my vehicle as well. Diagnostic Repairs is a absolute NO GO!!
