My car still not repaired two months later

I am short of words with the treatment I have received from Discovery Insure. I had a car accident in Harrismith on 20 Dec 14 on my way to Durban from Johannesburg. Only yesterday 17 Feb 15 after almost two months have they finally done the assessment at a panel beater. For the past two months the car has been sitting at the premises of the towing company. Today 18 Feb 15 I receive a message that they will not be providing me with courtesy car hire and I must return the Avis car I have been having since 22 Dec. My dilemma is that I have no car and I don't know when it will be repaired and Discovery Insure does not care about how Im going to drive to and from work. At the same time, they are deducting the insurance premiums. This is really shocking and totally unfair. Now I will have no car and not even know when my car will be returned to me. By the way, they have also decided to repair it in Harrismith which means I must see how I get it from there. This is totally unacceptable customer service from a company that prides itself as world class. I am reporting this to the Insurance Ombudsman. How can repairing a car be delayed for so long? It looks like I will get my car in June 15)
