Unacceptable Attidude, Service an Feedback

My father in-law purchased a vehicle from Auto Advance in Boksburg in March 2015. The vehicle was sent to BJ Auto Clinic for repairs to the gearbox from the dealer where the vehicle was purchased. The gearbox of the vehicle was faulty from day 1 of the purchase and it was picked up on a low bed about four weeks ago. We were promised that the vehicle would be ready in one weeks' time just to find out that the vehicle was sent to Johannesburg they could not fix it accordingly without us being notified. On approach to Auto Clinic we were unsatisfactory treated and this is unacceptable as they would not even tell us the whereabouts of the vehicle. I would surely not recommend any other client to take their vehicle to the same business and strongly suggest that this complaint be resolved a.s.a.p. as the vehicle is already 4 weeks with the Service Provider and we are now suffering loss of income because the vehicle is used for business purposes and is soly our bread and butter.
