Inconvenienced Customer

My car went in for repairs at VW Constantia on Thursday the 14.01.2016 and is still not fixed yet. I was promised yesterday by my service advisor that the ordered part will only come in this morning and that my car will be ready this afternoon. My service advisor Monique is a friendly young lady and though I don't like complaining and its not personally directed to her, I have been very inconvenienced to say the least. I rely on my car for commuting to work and to be without a car has been a major hassle. I was advised on Friday that the car would stay the weekend of the 16 and 17 Jan, though I did not like this I agreed as the car has to be fixed. I asked if there were any courtesy cars available and was advised that there were none.I then asked for a lift to take me to work Saturday morning, they agreed but I received no further communication and I had to make other means for transport to work. On Monday I was called that the car would be fixed today. Today I get an SMS that they have electricity problems and there will be a delay. I'm angry at the fact that NO communication (call) was made at all to me today to let me know as I was promised that it would be fine today.
