ABSA Freezing my account

Last night I tried to transfer money via internet banking and received a message "Absa IPP failed" not knowing what it meant I just ignored it. Today I'm out trying to pay bills and my card is declined. I then decide to go to the ATM to try and withdraw money I then get an error message saying "FICA PROBLEM ON ACCOUNT PLEASE VISIT BRANCH TO CORRECT" it's Saturday all the banks are closed, I call the the call centre one of their agents gives me the contact number for , Fica "FICA ONLY OPERATES MONDAY'S TO FRIDAY'S 08:00am until 16:30pm". I call the call centre again another agent tells me there's nothing they can do, i have to wait until Tuesday when the branches are open to assist me. I'm so aggravated, I did not get any notifications stating that I must update anything. Who will pay my interest? I'm closing my account with Absa on Tuesday and moving to a bank that will give better service. ABSA could have informed me prior to freezing my account, what makes it worse is that they wait until end the month to do this. I've got small kids and the one weekend we get family time I can't use my account.
