I bought a car from WeBuyCars I am not happy with their service and the work shop they recommend. The car had gearbox issues and they said I must take it to their workshop AED Silverton. AED took it to their other workshop The car was checked and quoted but the problem now webuycars said I must bring it to their warehouse went to AED they said I must pay R1500 for transport mind you I drove that car to Silverton and they took it to their workshop now I must pay a fee to bring it back coz the car is not drivable after checking it. So I think webuycars is working with this workshop to gain some money from us or silver lakes manager they benefit from this. How can I pay for truck to tow my car while I drove to their workshop please advise or I go to the media and all social network webuycars is a ****
