Standard bank deceased estate - not capable or interested in helping

The most frustrating experience in a long time. I have been trying to close my deceased brother's standard bank account for 4 months now ( which was unbelievably complicated) . Then I made the mistake to ask for bank statements I urgently need. All I get is automated responses that they they will be in contact with me. It started 7 days ago with emails saying they have a 48 hours "turn around" time and now suddenly I am on a 30 day turn around - to merely get a bank statement?!! This is beyond absurd. If you call the deceased estate number the lady keeps saying the turn around time is 48 hours, even if I tell her that have now waited 7 days for anyone to respond. Something is very wrong at this department. There is clearly no capable management
