FICA block not uplifted and not notified before my account was closed

My account was blocked on 21 March, I did not receive any notification or warning before they did. All my transactions were not going through and purchases were declined. I decided to call their call centre and I was told my account has outstanding FICA documentation and branches were closed. This morning (22 March) I took my docs to the branch and I told them I need my account to be activated ASAP. 3 hours later it’s not activated, I have an interview tomorrow and I need to book a 6am flight but I can’t because my account is blocked. I have called the customer centre non still trying to get it fixed but nothing has happened. This is ridiculous cause I might miss my interview if this doesn’t get fixed ASAP.
