credit/debit card purchase and they are offline

I WENT TO WOOLWORTHS ON SUNDAY TO PURCHASE A FEW ITEMS AND (AT THE FIRST TILL POINT IN THE FOOD SECTION} OFFERED MY CARD AS PAYMENT METHOD. MY CARD DECLINED ON BOTH MY ACCOUNTS AND KNOWING IT IS NOT MONEY THAT IS THE PROBLEM I ( EVEN TOOK BALANCES ON BOTH MY ACCOUNTS) REQUESTED THE TELLER TO PHONE FOR OFFLINE AUTHORISATION. HER RESPONCE THEY DONT DO OFFLINE TRANSATIONS BUT GOT ANOTHER TO ASSIST AND SHE GAVE ME THE SAME RESPONCE WHERE UPON I SAID THAT THEIR IS NO SERVICE AND TOLD THEM I WILL TAKE UP THE MATTER. I PHONED THE CUSTOMER SERVICE DEPT AND LOADED MY COMPLANT AND A MALE MEMBER OF THE SPRINGS BRANCH PHONED ME JUST TO INFORM ME THAT THEY DONT DO OFFLINE AUTH AS THEIR SYSTEM DOES NOT ALLOW IT. PLEASE IF I WERE TO BY FOR R10000 OR MORE WERE THEY GOING TO TELL ME THE SAME STORY. ALL BANKS HAVE A REWARDS PROGRAM RUNNING WHEREBY YOU GET POINTS ONLY WHEN SWIPING AND TO WITHDRAW MONEY IS EXPENSIVE AS THEIR SOLUTION WAS I NEED TO GO DRAW THE MONEY.
