Bad service! Worst Ford Ever!

My car has been at CMH Ford Kempster Randburg 3 times in a week, on Friday 05/10/2018 they advised me that they need to replace my master cylinder on my car and that they ordered it. Fair enough they booked my car again for today 08/10/2018 so they can replace it. I work with my car and had to organise a car for the other 2 days my car was in, today I do not have a car and its actually a big problem as I need a car to do my work. At about 13:00 they let me know that the part they ordered was not the correct one, how can that be as they work with the cars every day and they had my car on friday so they should have been able to get the correct part. I e-mailed back and asked that they still finish my car today as I can not afford to leave my car there again otherwise they should supply me with a car, one hour later and STILL I havent received any word back from them! That is totally unacceptable and very bad customer service. I am not impressed with the service and will definitely not be taking my car back there as this is not the firts time I have had bad service there!
