Horrible, inconsiderate and inhumane treatment from iWYZE

I was unfortunately involved in a car accident on the 27th of October 2019 while I was driving home. The other driver collided into me on the front left side of my car which lead me to spin and the airbags were deployed. The driver of the other vehicle apologized as he felt bad and he admitted to the police as well as my insurance that he was indeed at fault and that he would do everything to make sure things go smoothly for me but unfortunately he was uninsured. Myself and my 2 passengers were rushed to the hospital and I made the insurance claim the next day. Instead of making this situation easy for me, iWYZE immediately appointed an investigator who was nothing short of inconsiderate towards my situation and he was extremely secretive about his role in the process of the claim because all emails from him before signing papers were sent after he deleted his company signature from the email. Only after a while and after he had everything he needed from me did he leave on the signature that showed that he was an investigator . He kept calling me while I was in hospital telling me to sign papers that will enable him to investigate the car to see if I’m indeed telling the truth about my claim even though I have witnesses and the 3rd party’s statement. I had had enough of the abuse and I just did as I was told considering my trauma as I was still in hospital. I came out of hospital and the investigator immediately called me and insisted we go to the scene of the accident so he can take pictures. On the way there, funny questions were being asked throughout the whole drive about my habits but I thought nothing of it, bear in mind that everyone knew that I was not intoxicated at the time of the accident as proven in my medical records. The investigator insisted that I sign the papers that would enable him to take the car to a company called WAIDLER and from what I had read, I knew things were about to take a turn for the worst based off of their reputation and needless to say that after a month and a few days my claim was rejected based off of the report from waidler that claims that I was driving at 150kmh before the accident which wouldn’t make sense because there are speed cameras on that road, the same road that I drive every single day when I come back from work. I mentioned all those concerns and the investigator did not care one bit. Now I’m stuck in a situation where I have to pay for a car that I don’t have even though I was not the driver at fault for the accident.
