Santam Legal Department being unfair

On the 15 May my son was in a car accident, it was the other drivers fault. The other driver was driving a company vehicle, he did admission of guilt and signed the police report on the day of the accident. I contacted his boss were he referred me to his broker. I was struggling to get the details for the claim no answer insurance details out of the broker, after I had to tell him if I don't get the details I will take this further. On the 7 June I received the details eventually, contacted Santam Insurance, the consultant to me that the claim was referred to the legal department because the driver changed his statement to say it was his right of way. I waited 2 days no contact from Santam Legal department. I contacted them spoke to the consultant that was handling the claim I submitted all relevant documents as I was asked to do so. They can back to me end of June saying that they want witness or dash cam footage that I didn't have. I contacted the driver who caused the accident he told me that he never changed his statement still accept admission of guilt. I went back to the police station were the accident was reported the day of the accident and the police even told me you can not change your statement after the 1st statement he did if admission of guilt. I spoke to Santam and complained. Emailed were sent, I even tried to call the consultant change from the day I spoke to the 1st consultant it was handed over to 4 consultant that was working on the claim. On the end of the day emails going back and forward accordingly to Santam police report was one sided for my claim ***. I went to lawyer to assist me with this claim because they were ignoring me at Santam. The car is still not sorted out until now. Santam is even ignoring my lawyer. Something is not right regarding this claim and it is not fair. We were very honest from the beginning of this claim.
