Misinformation by your towing employee

On the 25 of June 2022 I was involved in an accident while still in the scene First help came to me and said they will help me to fix my Car and I don't need to Pay any cent because they're going to Claim from third-party and on Monday, they will call me so that I can get Courtesy in the mean time, since my car is not that bad He said it will be fine by 29-30 of June because I was still in shock he gave me a Paper to put my signature on that paper he ticked everything from my car like radio, Spare wheel etc, he never showed me the back Part of the Paper because I wasn't going to allow them to tow my Car, I was not well from the accident then Monday I was waiting for their call then on Tuesday I've called them to hear the way forward about the Car, that's when the Lady asked me for my email address then when I check on it they Charged me R12. 747.50 and say if I don't Pay they will take my car to the long term storage where they will double the amount daily so I had to go for loan so that I can get my Car back. Now my car is not fixed and I'm in debt, I'm in a mess because of your misinformation by your employee.
