Poor customer service

On the 26 of July 2019 my boyfriends car broke down while he was on a way to Harrismith and we called the insurance where the car was towed to grand central motors Midrand, we spoke to them on Monday and advised that there's a certain part that needs to be ordered overseas and wil take 14 days bear in mind that is the only car his using as his a field technician, he was willing to wait for that 14 days and he was called after the 16 th day confirming that the car part was delivered and wil be fixed before the end of the week, another call was given to him confirming that after the attempt of fixing the car it was stil damaged and wil have to order another part overseas again and wait for another 14 days, His job was now on the line because he had no car and no alternatives was given to him by the garage as the car is still under warranty, Another 14 days passed without communication from them you just have to sit and wait and hope for a miracle, he was assisted by a lady called Bontle as I feel she is *********** on her work because all she is hired for is to tell clients that the query is being logged and when she is not at work no one is willing to assist, on the 13th of September I decided to call Bontles office and was unavailable and I spoke to a gentleman and humbly requested a garage to give us a courtesy car atleast and was referred to liase with the head office first, we called immediately and was assisted by the lady called Phaladi, she seemed helpful in regards to logging a case and wil call us on Monday to give us feedback about the courtesy car where she Also failed to do so, we had to call on Wednesday to follow up and she just apologized for not calling like nothing major happened and promised again to call the following morning, Thursday we received a call from Bontle that the garage is organizing a car as parts wil be received in October and on Fri I must come get a car but she wil call first to confirm time, I waited for the call on Fri up until I called them and she advised she was at the managers office organizing the car and wil call me back, that was yesterday till now and the service Centre is not working weekends so now I wil have to wait for another week hoping that they will call us, I'm dissapointed about such poor service I received from them, not sure if I will ever use their service again
