Shocking insurance

We had a burglary at our house on 24/10/2022 and after going through the whole process we report it to our insurance company, for starters the lost adjustment company that they use required me to fill out a form in which I give them permission to do a BACKGROUND and ITC check on me, so I stated that they are now treating me like the ********, funny that they don't do background checks when they debit your bank account for your monthly payment how dare I claim... well that was only the start, they then are only willing to pay about 40% of the claim for the one item no serial number for the item they slashed the amount by half and on the other item with a serial number they say it is not proof enough!!! It is now almost two weeks since the burglary and nothing is resolved, I gave the replacement quotes on the 25/10/2022. I am still waiting for an update from them about when the payment will be made. I was also informed that they have paid out 3 billion Rands worth of claims last year therefore they cut claims this year a bit shocking, but they are trying to recoup last year's losses.
