Lacking to present valid evidence before decision taken

I made a claim on the 31 January to iwyze and investigation officer Trenton Shurbart contacted me and told me that this claim was given to him on the 6th of February 2023.He was making it hard for me to work with him as I was the only one almost everyday contacting as asking for any feedback. Last week Thursday (17 Feb 2023) he gave me a phone call stating that he has newfound evidence which also asked to represent that to me, but nothing was sent. Yesterday (20/02/23) after email sent on Friday inclusive of two management individuals (Kabelo and Adrian), a respond from Trenton and Adriaan advising me that they will represent newfound evidence to management for this claim to be rejected on those findings that have not given or shown to me. I am not disputingany of theri findings but it is my legal right since I am paying my premiums, to review that evidence presented which can prejudice me if it is fair, honest, and valid unless they have something to hide. I have requested all recordings from Trenton since last week and today requested again all evidence collected and recordings from interviewed witnesses and any footage's taken, nothing still sent to me.What makes the matters worse i dont have the car it was towed where storage is charged daily but they said the that place is one of their associates,costs will be considered based on that after decision.
