Bad Customer Service

I was involved in an accident on the 25th November 2015 my car was not in a drivable condition. I was not offered a lift back home from the scene. I was only given a courtsey car the following day (mid afternoon) and it took the company about 2weeks to assess the car. Once the claim was approved after a week I was notified that they can't find a panel beater nearby as companies are closed. They said they would get back to me on an alternative, to date I have heard no feedback from them. I have called to follow up and have been told someone would get back to me and still no one has. I keep receiving an sms that the hired car has been extended. But today I received an sms that the hired car needs to be returned on the 24th December 2015. My car however is still not repaired and I will have no car until it's fixed in January 2016. I feel I was to be informed of this at the beginning when I put in my claim not a few days before the panel beaters close.
