Worst place to take your car

Bosch service centre expid8 alberton do not take your car there . I sent my car in for overheating once just to make sure there was no problem. And For rear brake pads. They sent me a quote of R50 000 ridiculous. Said there was alot wrong with my car .I told them to fix the thermostat as they said it was not functioning properly and to put new rear break pads on. My car came back worst then it was. there was a huge noise on my back wheel water was running out my engine. This is after i waited 3 days for a inspection to be done. 4 days for a quote while my car was still standing there a further 8 days to fix the problem .only to drive it down the road water running out the engine. Wheel grinding against metal. Its un drive able . None of these problems were there to begin with paid R13 000 for them to mess my car up further. Admin staff have no clue what is going on. mechanics do not know what they are doing. We were told to pay a tow truck to bring it back to the shop. I refused as i sent a car there it was driving with no problems and now get told i must pay them R40000 to fix my head gasket which there was nothing wrong with. they are very over priced have no knowledge on how to fix cars and do not get back to you . Very unprofessional my car is not even worth the amount they want to charge to fix things that are not broken. I will never go back there i have to know take it somewhere else to pay to have the problems fixed they caused. After looking at all the bad reviews they have here and on Google how are they allowed still to fix cars. Why have they not been closed down yet.there must be something that can be done to have them investigated.
