Business Banking Bad Service

Hi i have recently opened up a new Business Banking account and i have been getting automatic emails to send through FICA Documents. i sent through these docs to the same email on the very first request sent. then I got a second request. i sent an email immediately to say that i did send the docs. No Reply. i called the business line (high Call volumes for 4 days in a row). I have now received the 3rd request for these docs and my account has been placed on hold. i have sent an email again and called again. nothing. i have even sent an email to Thulani Khumalo (Business Manager ) to inform him of the situation and no reply from him either. please can someone help me with this. i cant afford for my account to be put on hold right now.
