Waiting on repair -+2 months and dont want to canc

I've been have some problems with car since I got it. In the first place it to long just to sort out some of the problem witch not everything has been sorted yet. then there is a problem on the engine of the car. it's been almost 2 month now. and my biggest problem is that they don't let me know what is doing on. I have to phone and go and see them to see what is going on. and I still don't have the car and there was some things promised that wasn't delivery as of yet and now that I am requesting to cancel the deal. Danae says it can't be done. But I went and read up on the internet, they can cancel but it is up to them if they want to or not.
