King Price refusing to get camera footage proving their client knocked into me and no contact from them on 3rd party claim submitted.

I am a 3rd party of which their client knocked into. I submitted my claim on the 04 July and provided them with everything needed as requested. The accident was on the 27th June. I also requested that they get the camera footage of the accident as someone called me stating that they need my insurance details as they will be recovering from my insurance company. when I asked her did you even look at the camera footage she said that doesn't matter to her. She advised that someone else is working on my 3rd party claim. i have told them in all my emails that they only have 30 days to retrieve that footage from ADT and they are purposely not getting the footage because they do not want to pay out my 3rd party claim. The lady that called me said that their client are knocked at the back and me infront and that puts blame on me. I told her that her client was speeding, overtook me on the left on a bridge and the bridge was a one line. Knocked my front passenger side, drove off. I had to hoot and drive behind him to stop. Why are they not getting the camera footage??? Why has this person thats dealing with my 3rd party claim never contacted me telephonically or ever, as I sent numerous emails. What is going on and have you retrieved the camera footage????The is terrible service and then they still ask me can they quote me for a cheaper premium. No thanks, not with this service. I want a call with feedback. They not even acknowledging my emails. I get auto response that it will be attended to within 24 hours. Today is the 15 July 2022 and nothing.
