Poor customer service

The service I am receiving from Outsurance is so poor, we pay a lot of money to be treated like this. My car went in for repairs and they have not finished it at the panelbeaters, the courtesy car that the insurance took out is due and they don't want to extend the period, now I must be inconvenienced as a customer for something beyond my control. I spoke with one of the consultants called Daviya and she said there is nothing they can do to assist me, I must use taxi's to travel while my car is still with the panelbeaters.
