Unresolved Deceased Estate

My uncle passed away in Dec 2021 and to date we have not received any feedback from Standard Bank re his deceased estate. We have submitted all required documentation & called to follow up to no avail. We have visited the branch but we we’re told to continue calling. It’s quite disappointing from such a reputable bank when we’re going through such a tough time. I wouldn’t advise anyone to take a policy through Standard Bank.
