Outsurance does not pay out claims

On the 26th of January, I got into a terrible accident on the N14, an outsurance client on my left was driving at an extremely terrible speed in despite of the condition of the weather and as a result she lost controlled and hit my car terrible from the back and made me loose complete control. On the scene of the accident, I explictely explained the situation to the lady and showed her a trail from her vehicle directly to my car and I was told her insurer was outsurance and I should give them a call. I called outsurance few days later to make the claim and took them hours before a lady responded via email from their legal teams and asked for additional documents and imagery of the accident, which I sent them to complete the claim. She then takes couples of days to get back to me and to ask questions regarding the accident and I explained everything in details and she said she will get back to me on the same day. Days past by she does not call, I called outsurance back asking for the lady (Mathapelo Bokaba) and she was not available and sent her email with no response, the next day I call and asked to speak to her also with no luck, and i asked the consultant who answered the phone to explain to me what is happening with the case and the agent stated that the case was still being reviewed by management and hence why she couldn't get back to me (but mind you, she was not available on the day i called). After realizing that was a complete lie and it was something they said to easily get me off the phone, i told the agent i will call back. the next day I called back and she still didn't respond, and after trying to call her direct line she finally responded and said she was going to call me back. And when she called me back she said that my claim was denied and I ask her to explain to me why but she failed to make the case over the phone and said she will send the notice/verdict to me via email and I can appeal the decision. I waited almost for 3 weeks for her to send the email that she said she will send and still it did not arrive, yesterday (2nd MARCH 2021) i called her and asked for it and she said she will send it to me by end of business day and which she did, she sent a 3 statement document claiming that was the reason behind their judgment. I think my question to outsurance, why would you have such *********** people running your legal department, my life was at total halt when I was waiting for you to assess the claim, your client clearly did hit my vehicle at from behind. I couldn't go to work or meetings due to the accident but your consultant took their sweet time to resolve the matter and when they did, its clearly an indication that just did what was necessary to tick the completion boxes. There's no point of claiming you are the best in the country if you are treating everyone that makes a claim against your client poorly.
