Unsatisfactory or NO SERVICE

My son purchased a vehicle on auction from WeBuyCars. I need to go and pick up the vehicle in Nelspruit. I have tried contacting WeBuyCars on several occasions with no joy. Since then there has been no transparency from their side. I've been shunted from Pillar to Post. They keep giving me a new number to contact. There is no one that I can speak to. I just get a BOT everytime or I think that, that is what it is. Sometimes they answer sometimes they don't.
