car not yet fixed

I came from jhb and my fan belt broke and I got stuck on Sunday on the freeway in Durban. The car was sent to audi Durban and yesturday the service advisor advised that they need to order a part and cannot provide an estimate to me as to when the car will be fixed.I have a wife that is pregnant with no car and this is putting my wife at risk.my holiday is ruined as I cannot go nowhere. I cannot visit my parents who are in estcourt.this is the worst experience with audi.surely audi could have provided me with a car as the situation I am in was due to audi as the one in four ways did not fix my water pump properly.<br> with regards to me being inconvenienced someone has to provide me with a vehicle in the meantime as I the customer sees audi as not being able to do anything. I do not receive any feedback as to what is going on.please can someone sort this out as I am going to take this higher up or even to the paper's.
