Poor service and traumatic experience

On the 28th of December 2024 I went to the branch in Silverlakes to sell my vehicle to them which was purchased at the same branch 5 months ago, when I got there we were referred to a buyer he then asked what is the reason for us selling the car we told him the only reason we selling the vehicle was because of the fuel consumption as the car is an x5 5.0 V8, he then took it for a test drive and when the buyer came back he was happy with the condition of the car and said it drives well and we can continue with the transaction so I then signed a Sars form and another form which I believe was a form to handover the vehicle to them, while I was busy with John (another buyer )signing forms the guy who was testing the vehicle asked my husband for the keys again to go for another test drive which he said was requested by his manager, we then gave him the keys and he explained to one of his colleagues that he used all the fuel in the vehicle and he will need to pour petrol, then he was advised to take the company’s card to pour petrol to go for the second test drive.

A few minutes later I then asked my husband what is taking that guy so long( the buyer test driving the vehicle) as I was worried because I left my belongings in the vehicle then my husband said he is going for a smoke outside then I went outside to see where is the guy test driving the car. Whilst standing outside the guy comes back with our car damaged bad with a heavy knock on the engine … We then asked him what happened to our car why is it sounding like that?…

He was so rude and arrogant he told us the deal is off as our car is damaged he cannot take the car anymore we need to fix it as it was going to happen to us anyway, but I told him you were driving it you know what you did because you even came back with the mechanic which was worrying me.

We reported the matter it’s now the 31st and no one is assisting us instead we are going back and forth with the matter and the staff there. We are not getting to a conclusion on the matter and my car was damaged under them, and now my car is damaged and just standing .
