Struggling to Update FICA Docs

I have been receiving messages from Standard Bank saying My "business account remains non-complient because you have not submitted your business information and/or documentation, despite our request... Feel free to contact your Relationship Banker for assistance... I've have gone to the branch for assistance and was told they cannot help me. Only my relationship banker can help. I've tried several times to reach Mmutle, Neo N, my relationship banker via phone and email to no avail. I later sent an email to his assistant, Ngcobo, Mabongi M, still no response. Finally I sent an email to Poppy Leroux, the team leader. Still not response. SOS!
