Poor service and rude assessors and consultant ever

My experience is the worst of the all.I was involved in a car accident on the 28 feb 2020 .I was overtaking then suddenly the truck in front turned without indicating and i bumped into it.My car was towed by the insurance to the panelbeaters assessment was done and the said its a write off beacuse its uneconomiacl to repair as it s still umder warranty ok i tried to fight that they told its not your car the car belongs to the bank if we want to write off we will do so.Thrn I told them to go ahead then Lungile Tshabalala and Paula Khumalo sent m a consent form in order for the to access a trip log from tracker iddid sign it and sent it back after that Lungile said no now the only thing left is to be on a coference call with the financer to finalise the payment of outstanding amount To my supriseOn the 23rdMarch I received a call from ChadMarais saying he is town there is some data that he needs to extract from the vehicle nd he needed a copy of accident report and I must come him to show him the exact spot where the accident happend ok igave him ARreport we went to the scene he took some pictures to me i thought it was a process of writting the car was never told that they are still doing the investigation and before he came to my house he went to the panelbeaters only to find out the car ita no longer there it was towed to some storage in Gauteng on the 10th of march.Later that week i called him to ask him whats happening he told me that data he extracted he forwarded it to the analyst and they still busy he will call m as soon as they are done and asked me whether I saw the trip and told him I did.The following week Monday he called to say he got tje report and i was told that i was driving at the high speed i told him i was overtaking surely when overtaking you have to increase the speed and he said he is going to discuss the report and the me know the outcome of report .He called me to say that they decided to reject the claim and they are not going to entertain it .I sent hom an email asking for that report he said no he is not allowed to send it to me shouldI despute the claim he will forward it to the relevant department.I later sent him an email asking for his managers contact details he didnt respond after 3days i called him he said no i will send it two days later i send him an email to say i am still waiting for those contact he said no am not going to give you those details as the report is already at complaints department if youwant to dispute follow the procedure .For me they are not transparent with their clients the so called report they are relying on doesnt correspond with the tracker report and I am told that i have to pay for storage where the car is kept how because that car it in their provision and I am staying in NW and the car its in GP because of this lockdown my car its still at that storage. Why a m i being denied to speak to the manager so that i can get a clarity on my claim
