We buy cars Thohoyandou, Thavhani mall ****med me

I sold my car to We Buy Cars at Thavhani Mall in Thohoyandou. Initially, they offered me R212 000, but after negotiating, the assistant agreed to increase the amount by an additional R9 000. We then agreed that I would bring the car the following day. However, after collecting the vehicle, he only paid me R211 000, which was not the amount we had agreed on. On top of that, he was arrogant and showed no remorse about the situation.
