I need answers urgently

I have been making calls to Tymebank numerous calls, and each and every time the consultant on the line tells she is going to escalate my case and someone is going to handle my case. My father has been diseased in January this year. All necessary documents including the diseased Tymebank statement, ID's, death certificate, Letter of authority from the Master's office, every possible necessary documentation, including a Late Estate Account details have been opened. So all this has been sent through on 8 June already, and resent on 4 July. I have made numerous calls all promising me that someone will contact me, either via email or call 2 contactable numbers. To date nobody tried to contact me from this bank. I have never felt so helpless; to go through such a thing after your father has been diseased to obtain what legally belongs to you, is not fair at all. At a time when one requires the most support, this institution finds it fit to treat you like nothing. This financial institution is downright *********** to handle people's financial affairs properly and cannot be trusted because they don't even know to give you a simple email or call back.
