FNB harassment

It has been exactly a year (last one was May'22) since FNB requested FICA and KYC documentation from my husband. I have submitted all required documents, but they will come with new wonderful requests weekly now. Asked for a reason for this yearly harassment, was told a manager will be in contact with him - nothing!!!! Asked for clarification on the latest request dated 19.06.23 and get a SMS to say the account will be blocked!!!! FICA requirements are understandable and when reading up on the background for the need thereof, it stipulates it is for the prevention of money laundering and ********* financing. Absolute joke!!!! We have a royal battle every month to pay our bills (they can see on the history with the references used) never mind launder money or fund anybody!!!!
