terrible service

<p> hello</p> <p>Last month I took my car, BMW 525I E39 to Vision Motors in Gezina to fit cylinder and head gasket after the had overheated .They charged me R 26032.00 labour and parts which I paid.</p> <p>The car was released on 24/06/2016 with more problems than before, petrol gauge, speedometer , loosing coolant, leaking oil and still no power, noisy hydraulic lifters and bad CO2 release.</p> <p>I've returned the car three times to the workshop and nothing is getting better.</p> <p>They blamed the battery , which I have changed and the problems are still there.</p> <p>I want my complete refund so that I can take my a better service provider</p>
