2022 vw golf 8 gti faulty

I purchased a brand new vw golf 8 gti in May 2022. Within 3 months of purchasing the vehicle the electronics kept going off and on and the reverse camera stopped working completely. The vehicle was taken to Weiss vw who said it was a software issue. The first time they updated the software it lasted for 3 day. The second time the camera worked fot 1 day. They kept telling me that it's a factory issue and they waiting for vw south africa. I could not keep taking the vehicle in every few days so I contacted vw south africa who asked me to take it to vw Mccarthy durban. They could not resolve the issue without keeping it for 3 days. Vw south africa promised a courtesy vehicle. Mccarthy durban took 1 year to arrange a vehicle. Vehicle was booked in and it also had a gear issue.the part took 6 weeks to come from Germany. Every week they would tell me next week. The vehicle was with them for 3 months. After collecting the vehicle the reverse camera was now working. Within 3 days the rear PDC stopped working, the vehicle boot and door was rattling and there was loose parts under the steering wheel. Vw Mccarthy asked me to book the vehicle in again which I refused. It has been reported to ombudsman who doesn't even reply.
