3 online complaints & FNB still can't fix problem

This is the third time that I have lodged a complaint on this site against FNB for failing to effectively process my FICA documentation. They pay lip service by immediately responding on this platform with the same response that just seems to have been cut and pasted from a standardised template, but do very little else. Since my last complaint, I was assured by the FICA department and the Premier Banking Suite that all relevant FICA documentation was in order. Yesterday I contacted the bank to place a withdrawal notice on my savings account only for them to respond by telling my that I am unable to withdraw from the account, which has limitations placed on it, because of outstanding FICA documents. FNB's complaints line is just as useless, they just pass you from pillar to post. Seeing as this is the 3rd time in one month that the bank has failed to address my grievances, I suggest that a senior manager contact me, as nobody else seems to know what they are doing.
