Budget Insurance Claim process very dissapointing

I complained about the disappointment with budget insurance claim last week. I got a reply from Ntombi Marry-Anne Dlamini with regards to it and she advised that they declined my claim because of their clients side of the accident. That does not prove that their client is right. I was in my car when their clients driver knocked into my car. Firstly my vehicle has a collision detector and the diagnostic.revealed that my vehicle had a rear end collision. The witnesses from the other vehicles also advised that their driver did not even apply brakes. My attorney requested a copy of their clients accident report from Vusisiwe and as of this morning there was no reply from her. Is this how the insurance company does business and a well recognised company. Budget advised me that I need to prove that their client knocked me. My vehicle diagnostic proves that it was rear collision And I am still awaiting their clients accident report. Very disappointed with the company that they are not asking their client for proof I guess if I do not get results by this week Thursday I am going to the ombudsman or to Budget International
