Worst Service Treament

I have been treated poorly by Motus Renault's service department. It started when I was in Cape Town and my car was due for a major service with cambelt and accessory belt replacement at Renault Table View. I booked the car two weeks before and when it came time for me to take the car in, they told me that the cam belt and accessory belt had not been ordered. My car stayed in for an additional day when it was not supposed to. This week, my car had to be repaired for the wheel speed sensor and again the part was not ordered and I was misquoted on the price at Renault Northcliff. I ended up having to pay an additional two thousand rands out of my own pocket. I spoke to the manager and he promised to call me back and he never did. This has been the worst service I have received for a car brand I thoroughly enjoy.
