Bad service from Budget insurance

On the 24th January 2019 i had an accident. i was on a 4 way stop, and the other person did not stop the car and bumped my car whilst i was in the middle of the road. The car i was driving was not insured at the time, and i registered a third party claim with the person's insurance. Budget insurance took the car for assessment and brought it back, and they told me that they have sent a settlement offer to their client for approval. The next thing i was told that the client stated that she has witnesses and they need to contact them. This went on for more than 3 weeks which i kept on calling as there was no feedback from them and they kept saying they cannot get hold of the witnesses. Last week on the 16 March 2019, I called Rachel Madiba (Claim handler) to hear what is taking so long to get hold of these witnesses and what had happened to the settlement offer they sent to their client?. She told me that the claim was rejected due to the witness statement saying i was in the wrong and everything else did not matter but the witness statement is all they will use to reject the claim. What changed to the settlement being approved to now saying the claim is rejected.
