Terrible Service, utterly disgusting!

Really unhappy and regret ever taking my Car to this Bosch. I left my car with them on Monday 14th of March 2022. When my car was left it specificaly had 3 minor issues I needed them to check before this day my car has been driving and hasn't given me any major issues. They took 2 full days to qoute the qoute was over R180 000.The qoute had unnecessary parts on it that didn't need to be replaced .I then notified them the qoute was high and I would be collecting the car on Wednesday morning. I collected the car and to my horror on my way to work the car now had numerous issues that did not exist prior to it being left with them . The car now had misfires and the battery light had also come on. When we opened the bonnet we realized they did not put back the engine cover as well. I informed them immediately of all the errors now with the new error of the battery light being on they state that they picked up that there was a problem might I add during the duration of the car being there we were not informed of alternator battery issue nor was it on that large qoute they supplied us with. There was no mention of this at all .Only after I queried it they now informed me that there was a alternator battery fault. They refuse to take any accountability for what they have done instead of sending a technician to assist us they instead respond with a long lengthy email to cover their backs.Might I also add the diagnostic report was only emailed when we queried the new faults. The lengthy email was only typed and emailed after our queries. I can honestly say I wish I never took my car there . I was skeptical but decided to give them a try based on the fact that they are Bosch and also close to home. Biggest regret ever what makes it worse is their lack of empathy they have created more problems for us but refuse to assist. They claim to have have only done diagnostics on the car however to give a qoute that huge the engine must have been touched their technician fiddled with something to cause the car to deteriorate on such a short time ......been driving the car for so long without any major issue. PLEASE DO NOT USE THIS SERVISE CENTER . You will be highly disappointed and will be left with bigger problems in the end and further more they are unapologetic.
