WORSTEST SERVICE MY ENTIRE LIFE

I took my car to Steve's Auto Clinic a corsa lite 2006 so they check and fix for me high idling on my car. I asked the guys to check for me other faults with the car so I can fix them as well and I asked for a quote. They asked me to bring my car in on Monday at 7am.when I got there on Monday they took my car in and called a taxi for me cause I had to leave my car. Fair enough they had to check the car I did not have a problem with leaving it. I was told the taxi fare would cost me R295 from Centurion to Tembisa. I then agreed on that amount.Later on same Monday they called to say they did not check the car they will check next day. On Tuesday I then called later to check if they checked they told me they still working on the car I told them I will fetch the car on Wednesday morning because I didn't think they were being honest as I had to use the car on Wednesday to go to my late shift at work. After my call I got a quote from them that was R18600 when I checked the quote it was not corresponding due to the miscalculation. I took my time to check and calculate on the total of the quote it was R30 more. Wednesday morning when I collected the car they gave me a copy of that quote they sent on mail and they said I shud pay R370 for the taxi fee they ordered for me on Monday. I did not even ask them why now it's 370 cause last time they said 295. I then went to check all of the parts they said they needed to be replace. When I check the price of the parts of the car I find out that the guys are charging double that price and even more. I then asked the guys to requote and send another quote. Upon waiting for a new quote something terrible arised. The guys tempered with my brakes when I was using the car the brakes were now making noise I don't know what they did on my brake pads or disc's but my car was no longer in the same state I gave them in. My brakes are making so much noise like never before. SAC Centurion is the waste place you can take your car to. Those guys have poor communication skills I'm sure if I was not calling I'm speaking even today my car would still be there with no progress. I don't even know if all the things in that quote were accurate or not. Cause it seemed they were keeping the car and not checking it. I'm very disappointed. They added another problem to my car. I dont believe this. Worst place I have ever taken my car to. Never again.
