Bad service from VW the glen

It is unfortunate that i have recieved such bad service from the Glen VW. I bought brand new polo comfortline 1 Litre in September 2019 at VW East Rand Mall and it has already started to give me problems with gears this is the second time it breaks down on me ,I was stuck in the middle of the N3 highway and my car was towed to the nearest VW which was the glen(6 March 2020) .Left my car in the morning then later on that friday i called was told by service provider that they will only start working on the car on the following Monday,the service provider was sick on Tuesday and Wednesday and was told that they not can assist me because she has the files on her computer on Thursday i then called again she told this is when they only going to start to strip the car,most of the time when i call they say her line is busy or there's load shedding or lines are down or can they take a massage for my service provider to call me back which never happens i would end up calling time and time again I then decided to escalate the matter to VW SA about the bad service on friday the 13th March 2020 then they said they will do investigations. I was only called Monday the 16th by the glen that my clutch is burnt and warranty won't cover it,i called VW SA that im not happy with the diagnostic and want more reason/answers/proof because Im not a new driver and this is not my first car they say they will do investigations because they too are not happy with the Answer they got from the glen,it's been 3 days i havent received anything concrete as to when my car will be fixed they only say they still gathering information to date (19 march 2020)i have not been offered a courtesy car,Ive been higly inconvenienced from something that could have been fixed in a few days
