Poor Service at VW Bryanston

My car's Abs light has been going off since Sunday so I decided to book my car in the Tuesday to get it fixed. I picked up my car as normal assuming it was fixed as they replaced the brakes. Driving home I realized the problem wasn't fixed I had to take the car in the next day again not understanding why they didn't do a proper diagnostic . What ****ed me off is that they only got back to me later in the day and they told me I wouldn't get my car and nor would they be able to give me a courtesy car whatsoever. I'm seriously disappointed. As to whether I would return my car here. It's a no for me. I think being customer centric in your services is important and o didn't get that. So that is why I am giving them a poor rating.
