Failure to take accountability

Got into a car accident on the 29/12/2025 and only had my right-hand side mirror damaged. Called my insurance company, Budget Insurance, for assistance as I still had about 400km to drive and it wasn't safe to do so without the side mirror. Budget Insurance towed the vehicle, and I was informed it would be taken to Ray Gieses's Body Shop on Monday 01/12/2025. My car sustained additional, severe damages which I was told were caused by the towing company. Budget Insurance handled a secondary claim for these damages which was approved in January. These additional damages are causing delays due to parts arrival, according to the panel beater. I am requesting the to extend my curtesy car usage due to this, they are refusing claiming part delays are not covered, however those delays are due to damages caused by their service provider. I am receiving no communication from the panel beater regarding completion of these repairs.
