Very unhappy with We buy cars!

On 25 May 2024 i bought a vechile at We buy cars at the dome. For R120 000. It is a dekra platinum status sticker. But the documents they sent me shows a gold status. Underneath the platum sticker there is a green sticker. I want to sell my car now because i live on a farm and have to drive on mountain roads. My car stands in town because i dont want to damage the car. 5 months of having the car they only want to give me R70 000. And in the reason they say is my car is resprayed!! They did not tell me that when i bought te car! No damage is on the car that was the put there while the car is in my name. I bought the car cash. The normal wear and tear was like that when i bought the car but now i am being penalised for the condition i bought the car. I know the value of the car may drop n few thousent but R50 000?!!!! And i did ask specifically for a car of platinum status because i dont want to spend on fixing problems but why did the papers state is a gold? I am very unhappy and want to go further with this. Because the value of a vehicle cant drop R50 000. In 5 months!! The vechile is in the same state as how i bought it!. I have to buy a bakkie but not with the amount they offer me. Currently i live on a farm 28 km out of town with no transport.
