Worst after sales experience ever

I received the worst after sales experience ever, I bought a brand new Sandero in April 2021, I collected my car on tge 17th of April, the following day which was the 18 I realized that there was interior damage and a scratch on the car I immediately informed my sales person and said she will inform the relevant department, after some few days I received a call to inform me that I was not covered even though it was about 24 hours since I collected the vehicle, I had to take an additional cover which increased my installment.

Secondly I had a permit and and waiting for my registration from the dealer, a permit is obly valid for 21 days, I informed my sales person that my permit is about to expire and I had trip to Limpopo she promised that I would have received my registration by then, unfortunately my permit expired while waiting for registration and I was advised that I can change the date on the permit and extend it of which I my self know is against the law.

Thirdly I currently have a problem with my windscreen and windows, and central lock I have been doing up and down to the dealer trying to get it sorted, obly to be told not covered, my car was less than six months and it was brand new, i wasn't expecting to have such problems so early. I had an appointment with the manager, they took my car for about 2 weeks, before i could receive my car i had an email from the manager informing me that my car had been sorted, but when the driver came with my car my windows were still the same, only the central lock being sorted, as of today am still not being assisted.

One thing I have realized about the dealer is that they are very good they trying to make sales but after that you are not covered for anything.
