Webuycars after sales terrible service.

Great when you buying after service is terrible, WeBuyCars and Dekra need to be invistigated seems like this cars are passed without being properly checked... I'm paying for a car they have to cancel. Car collected on Monday for cancellation process, car usage charged for the month, which I paid once I was told. Month end now guess what instalments goes off my account so double payment for the car WeBuyCars has in thier possession which was approved by Dekra as roadworthy. This is like buying from any other car sales garage. Yesterday I spend wasted time at thier branch at the Dome and the best thing they said was we don't know what tell you it's the process it's in thier "final stage" what does final stage mean? No direct answer.
