Std bank online business account a headache

2 days back I app**** for a business account through bizportal, I received an email with ref no: NTBMMB***, however the email address to which I need to send my POA as well as any other email address I tried to make correspondence through are just not working, my emails remain (queued)I tried every possible means but failed and worse of all, I only had 24 hours to send these documents. At first I had thought the error was on my side so I sent emails to other addresses and it worked perfectly fine but this bank. I do not have much time, I need the business account urgently. The fristration of being stuck like this is not what I expected from Standard bank.
