Standard Trust worst bank or department ever I rather give my business or work with a bank that cares about customer service

Standard bank estate department is one of the worst I have ever dealt with they cannot look after a 6 year old kid when I have a maintenance claim against the estate it has been approved, nothing to take care off the child they have only paid school fees and transport everything else they do not want to do we're does he get food and clothing and shelter from as well as he is very sickly and there is funds in the estate account and they say we need to give receipts how do you get receipts with no money it is currently 1 year 7 months with them and they simply do not care and ignore emails and phone calls
