Standard Bank unable/unwilling to help an offs**** customer

I’m in New Zealand and have been battling for about a year to get access to my Standard Bank cheque account. Admittedly I think I initially got blocked out because of an unpaid account I wasn’t aware of, however after a years worth of emails and expensive phone calls all I’ve been advised is to open a new transactional account but I have to be at a branch to do so. I’ve explained this conundrum to a lot of Standard Bank employees which are keen to help but do just say I have to visit a branch, when I explain that I’m offs**** I get a blank “sorry I can’t help”.

Please help me Standard Bank!! I want to keep my investments with you but you’re making it real difficult to do so.
