Poor customer service

Poor Customer Service Bought a second hand vehicle there on 3 March 2025 on 27 March 2025 I informed them car suspension has unusual sounds coming from there and other issues. I was told to take car to Nissan East rand where they say car was checked before being put on sale. Nissan Eastrand confirmed all the issues I was facing a gave me a quote to give to them. After that I have been ignored. A week ago I asked for the 125 point check copy only to find out all the issues I was facing were known and on that document which was done 13 December 2024. Salesperson **** to my face when I went to collect vehicle and said everything was fine, no issues picked when the car was checked. I believed him because I thought a reputable brand like Hyundai wouldn't dare do such to a customer. Lesson learnt all these dealerships are the same.
