Bad service

My car has been at Noval Motor Ford in Paarl a month. No work was done on the car for 2 weeks, the first two weeks we where trying to get approval from S.A Warranty for the quote of the service. The quote was finally approved 26 February 2015. I approved the quote and give the service department the go ahead to start repairing my car. At this date I obtained confirmation from Eric that the service will take a week and that I should get my car back late next week (6 March). I phoned the next week to ask the work in process, they have not started to service my car yet, but the car will be finish next week. I phoned again today (18 March 2015) for the work in process, still they have not started do work on my car. It is now two weeks that I am waiting for my car. My job requires my to work late evenings sometimes to complete assignments, these assignments are now being extended because I don't have transport to work late evenings. The most disappointing part of this is that I have never been disrespectful to the staff of Noval motors for the Bad service that I am receiving. I do feel that the service may be as a result of my skin color. I have Ford KA.
