SLA too long

I had a car accident on 9 June and my car was towed to Auction Nation in Bellville South. After more than a month of the insurance investigation the claim was finally approved and my car towed to Mullanys Auto Body which is more than 60 kilometres from my place. It turns out that while the car was in storage my side mirrors were taken from my car and new mirrors have been ordered. Mullanys received the parts more than 2 weeks ago but it will take another 2 weeks to get my car back. That means I will be without a car for 3 months if the possible date to get the car is 8 September that is not even a guarantee.
