Very bad service looking for any reason not to pay out

I had a very bad experience with a 3rd party claim with Auto and general, their client drove into me, he then turned around and said it was my fault they closed the case, I contacted their client and asked him how can he lie like that he said he never said that, I got him on a conference call with the insurance and he admitted it's his fault, the case got opened again wnet for review and they still decline saying it's my fault the only way they will fix my car is if I get a footage to prove my innocencezyet their client mentioned in his EMPD report that it was his mistake
