Small Businesses Count For Nothing

Even though I understand the challenges that financial institutions must be experiencing now, I have been trying to get a response from Standard Bank Business Assist for more than two weeks - You can only contact them by email to which they send an automated reply and then.... NOTHING. My Business Banker in Herm**** appears to have left the company without forwarding details of his replacement and so I am high and dry receiving daily sms's saying my account is in arrears despite an offer from Standard Bank before lockdown of a payment holiday to which I opted in.

If anyone can suggest how I actually communicate with this faceless ineffective behemoth I would really appreciate it.
