Very unhappy, unsatisfied, no transport?.

Very unhappy, unsatisfied, still no car? ,traded my car for a BMW X1 and has been 4 weeks without any car ....Webuycars are full of storys.... I traded my Ford figo for a bmw x1 at Webuycars Centurion branch , the BMW was Deka approved and the car advertised as in very good condition ,so that's why we could select it as a option to finance.. after the deal is done the car started with problems on the first day , I reported it to webuycars and they said I must log a complaint, after logging the complaint I still did not get any reply and was forced to call and log a complaint... after 1 week of struggling the car was collected by webuycars because it was not able to drive anywhere. They sent it to a workshop called grease ****** since the car has been at the workshop for 4 weeks now!! I am struggling everyday to get feedback from webuycars . I have to call the workshop everyday and call the claim department everyday just to hear that the one is waiting for the other.. Webuycars is not treating this as a serious matter as I have to call and email webuycars everyday for a followup ?? I asked webuycars from the start to cancel the deal and help me with a car to get to work and back since I traded my running vehicle !!! for this bmw??? They are full of excuses and said they can not help me with a temporary vehicle and have to follow the procedure by doing the claim?? And use my motor warrety?? But never follows up or give any feedback ,if I don't email they will keep quiet ... the workshop picked up that the waterpump is fulty the thermostat needs to be replaced and also the radiator is leaking, the battery needs to be replaced, the car has 3 engine oil leaks the head of the motor needs to be send in for engineering, valves needs to be changed ??? And the front stabelisers needs to be replaced ?? But when this vehicle was financed it was advertised as all in very good condition NO oil leaks ??? Everything was advertised as very good condition and that's the reason we were abel to finance for the fact that everything is in very good condition... the Decka report means absolutely NOTHING!!! .. before finance the car needed a service and 3 new tyers, they where fitted but the one that was not changed was inside out (wrong way rotation ) and bigger than all 3 other tyers ? ..they claimed they did a service but did not even pick up any oil leaks ?? I am still waiting for a response from webuycars..I still have to Uber to work or borrow sumones car ,I still have to pay the installments every month but have nothing to show for it?. I am very unhappy and would not recommend webuycars to anyone..I will also keep updating on this problem till this problem is resolved !!!!
