Highly disappointed by bosch in Soweto

The worst service i got from Bosch service in Soweto this is the fourth time taking my car to this people and always when it comes back the worst happens then yesterday it was a cherry on top i would never recommend bosch service from Soweto to anyone i bring my car for service then the following day it has a problem four times first time my driver told me there was a sound in the front closer to the engine only to find out they didn't tie something second time it was a battery fault third time it was a starter and fourth time it was the wheel so i take my car there to spend close to 4k then i no t'he following day i still have to spend money for another problem that I'll find after taking my car there I'm really disappointed then when i call the manager his not even calm to listen to my story he just shout at me with listening to understand he was just listening to reply to what ever i was saying to him he just keep on shouting and telling me is not his fault for what's happening in my car... I'm really disappointed.
