Horrible service from Standard Trust Limited - Cape Town

The interaction, or rather lack there of, is horrible! My mom passed away just December 2020 and we (me and my brother) received the will a month after requesting it. We also requested an inventory of our mother's estate in Feb, we have not received anything of that nature. The only we did get, randomly, are some monies (which we have no idea where they come from and whether or not we received the correct amounts). The last straw is the current one I'm dealing with. I had a geyser burst almost 3 weeks ago and I need an insurance claim to be processed. I can't do it myself as the house and insurance are still under my late mother's estate and I do not have power over the estate thus the estates department needs to submit the claim on our behalf. I've been going to the Cape Town offices BEGGING them to do their job and assist with no avail. The only thing I have been promised is a call back in an hour every time I call but I have not received a single call that has led or is leading to the resolution of this matter. I told them I was in my first trimester and the up and down to the ceiling, as the water was leaking through the ceiling to the wooden floor thus I had to wipe it every now and then as the water was still coming out even after I had closed the water supply to the geyser. This did not seem to matter to them as none of the managers of the estate have contacted me with a solution nor a work around. I know as black people using the basin to wash is historically our thing but my mother worked really hard to make sure that she upgraded our lives thus we cannot be expected to continue with such practices in this day and age. Please assist!
