VW Polo TSI 1.0 2018 Model – Mechanical Failure ☹ ☹ ☹

I bought a brand new VW Polo TSI 1.0 2018 model in September last year (2018). It has already been taken to VW for repairs twice due to factory faults. Firstly, the handbrake and then the back seat safety belt. This was on advise from VW. On Friday, the 12th of July while driving on Harley Street in Randburg the clutch malfunctioned. I couldn't change gears. The car stopped and I switched it off and restarted it. The clutch was vibrating and I still couldn't change gears. I never experienced this with my old VW Polo which I drove for 9 years. I called VW Road Assistance. The car was towed to VW Melrose Arch as per their instructions. The person who assisted me at VW told me that they didn't have courtesy cars as all were booked until Tuesday, the 16th of July 2019. I told him that I will need a car to get home that day and to get to work on Monday. He couldn't help even after speaking to his manager. I then called VW head office to complain. The person I spoke to said the query will take 48 hrs. I said I couldn't wait that long as I need a car by Monday. He asked if I spoke to the salesperson where I bought the car and I said no. I then called the salesperson, Tebogo at VW Mastercars in Arcadia and after he spoke to his manager he said that they will not be able to give a courtesy car as the car was not with them. He further said that someone needs to facilitate the towing of the car to their dealership in order for me to get the courtesy car. I asked of who is supposed to do that, he said he'll come back to me but never did. The following day I tried calling him several times, and he wasn't answering. I then tried the landline and still couldn't get hold of him. He sent me a WhatsApp to say that he was doing a test drive and couldn't answer. He asked if Katlego, the workshop manager called. I said no. He then gave me a landline to call him/her. I got transferred to the workshop department but the lady who answered the phone kept hanging up on me whenever she tries to transfer me to Katlego . I tried several times until they were no longer answering but hanging up on me. I sent the screenshot of ‘the number of times’ I called, to Tebogo and said that they don't seem keen to talk to me and that I still couldn't get hold of Katlego. I'm left with no car and frustrated. It hasn’t even been a year and already I’m experiencing issues with this “brand new” car ☹
