Locked account

Good day,<br> <br> FNB have locked my account because they say I never FICA-ed my account, which I did 3 times at the branch and emailed the documents to the address provided another 4 times. They keep saying they have the documents, but yet my account is still locked after 4 days. I have spent the entire day on the phone trying to unlock it, but with no success. I really do not understand why it takes so long to unlock my account, first of all, and secondly, this is due to their error but nobody is willy to assist. I am extremely frustrated.<br> <br> Regards
