Insured Citroen at panel-beaters for over a month, awaiting parts..

My insured citroen was involved in an accident. Insurance approved the claim and sent the car to the panelbeaters who could do nothing as there are no parts in the entire country. The parts had to be ordered from overseas and its now been over a month and not a single part has been fitted to the car and the panel-beaters dont know when the parts will arrive, so the car is sitting in their warehouse whilst I need to borrow a car. Only with this brand will you be stuck without a car for over a month and no ETA of your car being returned and no communication from citroen.
