Bad standardbank trust and communication and insurance

We are struggling to finalize the lost of my mother from 2019 we never get answers as this is now 5 years nothing has been done my dad had to sell his previous property to save this property that is on my mother's name and for that reason standard trust took all the money and just paid the new owners as they thought it was fit Evan though non of the quotes were the same he paid twice for a legal coc that they said it was *****, we had a insurance claim done on this property as the property was totally vandalized it was approved and when we wanted to start fixing the property standardbank insurance withdraw the money and said we may not claim for the Same as before without anything being done in the time we were without water and electricity and my 25 year old daughter past away all the stress for this property staying with no windows no electricity and no water we were struggling until now no reply or any communication regarding any of the matters the property has not yet been registered on my father's name as we knew standard bank was this bad we would have never ever asked them to handle the case
