Worst service ever

My car has been standing at HJ Bosch & Sons since end of May 2015. They do not contact me regarding the status of the repair, and when I phone them the service is terrible (especially from the panelbeaters themselves). Last week they said my car will be done by tomorrow, but now it is next week again.<br> <br> Aside from this, when I phoned them to hear why they are taking so long, the panelbeater had the audacity to say that it is my fault that I don't have a car. I don't think that is professional at ALL, aside from the fact that it wasn't my fault in the first place.
