PAYING FOR SERVICE NOT DONE / NO FEEDBACK

I had my booked in for a service 24.03.15. On the same morning Kevin phones me and 'advices' me to have me wheel alignment and balancing done : Ja no I advice all my clients to have it done on 15000km. Ok Kevin fine go ahead do it. What does it cost Kevin? R342. R342 later, the car still pulls to the left. After contacting Kevin at 09.43 am and telling him what is wrong he tells me to bring in the car. I refuse to do so, he did not do me a favour nor was a courtesy he afforded me. I PAID!!! When I told him that he said he'll phone me back. 11.19 am Kevin is still returning my call. Phone back, phone back, get placed on hold, Nicole doesnt sound very enthusiastic. Phone Ronald 11.22am, tell ronald my story, pretends to understand, he'll have a look at it: Im a qualified whatever. 3 days later...NO RONALD after he said he'll phone me back at 15.30PM. Im not quite sure if anything was done on my car now. Wiper still leaves a streak, clutch still sounds the same. Anyone out there who I can just GIVE my money to? Or maybe i should wait till things happen and I can take legal action...I dont know you tell me
