Bad service

I bought a car in December from WeBuyCars, and the license plate was registered under Northern Cape. They assured me they would send a GP (Gauteng) plate, but obtaining it turned out to be quite a hassle. When it finally arrived, there was no license disc included. Unfortunately, despite my efforts to reach out for assistance, no one seems willing to help. Now, I’m unable to drive with an expired license disc, and it has been two months since I started reaching out but still no luck.
