Nedbank FICA Process appaling , and no service from their Complaints dept

I am extremely frustrated with the Nedbank Compliance division that does their FICA process, and their complaints division which chooses not to respond to complaints even after following up. I did submit my FICA docs in May this year , and had to do it twice because I was getting reminders after the first time. Fast forward to Oct, I got sms's to submit myself for FICA again, frustrating give the interval between this request and the last FICA process. I duly submitted my docs at the branch where you have to ensure an hour waiting time. I am still getting the remimders now threatening to close my account. I reached out to the complaints dept via email twice and no response. I bank with another bank and can do their FICA process digitally and am now tempted to move all my business to them because I am a very frustrated client.
