Smart Block Nightmare!!

On Tuesday (13.12.22), I had money transferred into my account - fnb to fnb, however the funds did not clear immediately. When I went to enquire at the bank the following day, I was told my account has been put on Smart Block - which the consultants seemed to not even understand what is that and why it happens. I have been sent from pillar to post and till today no assistance, my funds not yet released into my account! I am highly annoyed and irritated as I need this money to make payments! I don’t understand that when FNB introduces new products does it not take their staff through training?! This is ridiculous! I need that money in my account by close of business day (14.12.2022). What a let down from FNB
