NO REPLY FROM PRIVATE BANKING OR BUSINESS BANKING

I have sent numerous emails to my private banker regarding information I require from him in order to send forward documentation to GEPF but as of today I have had no reply, not even a read receipt, I even sent an email to the Private banking email address but also no reply. I have also tried to contact business banking to close an account for a company that has ceased business ones again no reply. Seems FNB emails are not being manned at all.
