WeBuyCars worst service ever

Worst service ever from Brackenfell branch and then sales person/maintenance manager. Bought a car in mid April, reported problems with the cars cooling system within 20 days after purchase and they told the mechanic to claim repairs against my warranty. I submitted a complaint at the customer care center and received a message last week saying the claim has been approved and ever since I have been trying to reach the assigned agent but they don't call back or answer emails. My warranty already paid the mechanic for the repairs and I want to discuss this with WBC but no use...I will never refer anyone to purchase a vehicle through WBC. They seem to be dishonest on the Dekra reports and I had many people make the same statements!
