Payout Query- Insuficient to cover the lost items

In October I had ******* at home where my car and some items were taken. 2 assessors came to do their assessment, and they paid for the car. I also submitted a list of all the items that were ******, some of them were in the car.

Weeks went by without any feedback until I made a follow up(s). FF, after more than 2 months of waiting, I was given AOL of R52383.33 and I requested a breakdown of the amount since it was less that what i was expected, then they sent a breakdown that starts from item 11 and a reduced amount R35393.07. Some items they are paying less amount that what they actually cost in store. I am really disappointed with the amount received. Worse part is that there is no direct contact with the claim handler (Claudia), she just passes the message, and whatever she decides is final.
