Purchas of vehicle.

Tried to buy a bakkie from them on 25 March 2024. They were all good till I paid the deposit. Then the story changed. I had to pay the full amount. I did. Then I had to pay another amount for TAX purposes. Then they got rude and ill mannerd. Till today 08 May 2024. I have not received my vehicle nor my money back. No one calls back or answers my questions. Will be opening a ***** case against them.
