Bought a car with problems which was not disclosed, and service done but service records cant be supp****

I bought a car at Anglo car dealers at Benoni, on the 18 July 2025 all paperwork was done ,I waited for 5 days for the car while they say they took the car for a service as well as to repair the Tail light ,they phoned the 25 July 2025 that the car is ready ,but they can't supply me with service records as well as the tail light ,they say the tail light is on backorder ,but there is no correspondence till today ,I encountered a lot of problem with the car including the windscreen as well as the parking brake, and the ignition coils and Tyre sensor which was not disclosed to me which some are still a problem, luckily when the car didn't want to start due to loose battery terminals ,I Realized there is not enough coolant water in the reservoir ,This was my first time ever in history of purchasing a vehicle to encounter service like the one I received
