Poor service from a car dealership

I had an accident in April and made a claim with IWYZE which was authorized a month later and my car was (or has been ) with Technostar (in Durban). I was told that it was going to take 2 weeks and within that there was an unforeseen damage that was noted ( I was told), and today marks the 6th week with no car. I am highly pregnant and the problem with these guys is poor communication. I have been spending my airtime everyday to find out what is going on but I would only speak to the receptionist who always takes my numbers and tells me that the person handling my car is going to call me back but does not do it, only does it 2-3 days later. He would tell me that the car should be ready on this day, when that day arrives, they do not call to say it won't be ready by that day. It is painful, I do not want to lie. I am extremely exhausted.
