credit card dupplications

HI I APP**** FOR A CREDIT CARD A FEW YEARS AGO AND RECEIVED THE CARD AND USED AS NORMAL. I THEN WENT UNDER DEBT REVIEW AND AFTER A YEAR OR TWO WHEN I WAS FINANCIALLY FIT TO GET ALL MY DEBT PAID I WENT TO STANDARD BANK TO GET A SETTLEMENT AMOUNT. WHEN THAT WAS GIVEN TO ME I PAID MY AMOUNT TO CLEAR MY NAME. THEN A COUPLE OF MONTHS LATER I TRIED TO GET CREDIT AGAIN I WAS INFORMED THAT STANDARD BANK CREDIT CARD IS STILL BEHIND WITH FURTHER INVESTIGATION I LEARNT THAT TWO CREDIT CARDS WAS ISSUED IN MY NAME AND I PAID THE CREDIT CARD THAT I NEVER RECEIVED. TELL ME STANDARD BANK IS THIS THE WAY THAT YOU TRY TO ***** FROM YOUR CUSTOMERS? EVERY TIME I PHONE YOUR EMPLOYEES TELL ME THAT EVERYTHING WILL BE SORTED OUT SO TELL ME HOW LONG DOES IT TAKE FOR YOUR USELESS EMPLOYEES TO SORT THINGS OUT???
