FICA Account Freezing

Hi, FNB has contacted me probably over 20 times (multiple parties: vendors, call centres, branches, etc...) now around exactly the same issue that my business cheque accounts will be frozen unless I comply to the FICA requirements. After every single contact, I have submitted the requested FICA documents, only to find out a month or two, or a year later, that I have not submitted the correct documents and that my accounts are under threat of being frozen. I have also gone to the branch twice to discuss this face to face, and on both occasions took all required documents (as far as I was made aware) with. After submitting the last set of documents I received no feedback from the [Email Removed] dept, just to get another sms today saying that my accounts will be frozen. I am now fed up with this terrible FICA process, which is obviously broken and does not work at all. What can I do to once and for all submit the correct documents in one go to have all three of my business accounts FICA approved. Please, please, please tell me how I can do this so that I will not get another sms next week saying that my accounts will be frozen. Thanks
