Eastvaal Secunda Ford

I am in deep disappointed of the service that Ford Secunda has offered me.
To begin with a bit history to my disappointments, I took my car to the dealer having an air-corn problem. When I put an ignition on, there is a sound on the dashboard, they told me its aircorn regulator, which they replaced. Within two months it started again, and I took my car again to the dealer, then they said the same thing that its a regulator but its left and right then its left now. Within two months it started again then I took it inn again, now its the third time. Then my car came back without blowing the air from the air corn and I took it inn for the forth time now. They told me that now its evaporator which they have to order and told me when my car will be ready. On the day that I was supposed to get my car, I gave them a call just to check when my car will be ready for collection, then they told me that they have not yet started with my car they will do it next week. I waited for a the whole week now I have to wait again for another week!
