Pathetic insurance cover my car is being held hostage after rejected claim

I was in in an incident end of February 2020 claim rejected in April. I was just sent a mail with a number in KZN and told to go collect my cars and pay all the fees for storage and towing to get my reparable car out. Firstly what's important to note is been with them for almost 2 and a half years through broker called Successio I've suffered a devastating loss and they cant lift a finger to help. to this day I don't even know where my car is and what payments will be expected of me which I'm not even suppose to be paying for in the first place. Insurance is suppose to indemnify you not bankrupt you. My car is now being held hostage during level 4 when most business are open and I will no doubt be given a hefty storage fee which they are suppose to pay for in the first place since they authorized my car to go there without my knowledge or consent. I could have just parked my car at home. Its being stored at Mandos holdings who are unable to make a simple arrangement to release the car but will happy to charge me storage fees.
