HOW CAN ABSA BLOCK MY SAVINGS ACCOUNT?

I, AS USUAL WENT TO THE BANK TO WITHDRAW SOME MONEY FROM MY ACCOUNT, BUT WAS SHOCKED TO REALISE THAT MY ACCOUNT IS BLOCKED WITHOUT NOTIFICATION BY PHONE OR SMS, I WAS THEN TOLD THAT I NEED TO BRING COPIES OF MY ID AND PROOF OF ADDRESS FOR FICA PURPOSES OF WHICH I DID, TO MAKE MATTERS WORSE, MY MONEY WILL ONLY BE ACTIVATED IN 3 MONTHS' TIME, I HAVE KIDS, ACCOUNTS TO PAY, BASIC STUFF NEEDED LIKE FOOD, SCHOOL FEES, THIS IS TOTALLY RIDICULOUS, AFTER ALL, ABSA IS MAKING A LOT OF MONEY FROM ME, BUT BEING TREATED LIKE A USED ****** IS UTTER DISGUST, ESPECIALLY FROM ABSA, A MEMBER OF BARCLAYS...
