Lack of skill to update FICA info

Not too long ago I wrote a review about trying to change my address with FNB and it taking over 2 years to achieve. In that process I was told I have to be Fica'd again. Please note this is for a business and the documentation required is quite extensive. I submitted all the documentation for the change of address and was even told by the person dealing with my enquiry that she has never encountered a person complaining so much about not being able to change my address. It was apparently "abnormal". Well this abnormal person once again, just about 6 months later are receiving requests to update my Fica info. I have phoned, left messages, phoned again, got the wrong reference numbers and phoned again. First I was told the lady responsible will phone me back, that never happened, then I was told, no no info is required my info is up to date and the reference number is the date and time and I will be removed from the FICA e-mails. I once again got Fica requests and phoned again as I see my info is still wrong. I submitted the form and was told it will be updated, this time I was given a reference number. All this was done 6 months ago, yet again it is wrong. Something is seriously wrong at FNB.
