First National Bank
Money debited twice

I USED THE CHEQUE ACCOUNT AT DIFFERENT RETAIL 16.12.2013 STORES AND THE MONEY WAS DEBITED WHEN I PURCHASED WITH THE CARD.YERSTERDAY WHEN I CHECK MY BALANCE IT WAS DIFFERENT AND WHEN I ASKED THE FNB CONSULTANT, THEY ADVISED ME THE MERCHANT DEBITED THE MONEY AGAIN HOWEVER WHEN I PURCHASED IT WAS RESERVED
AM PUZZLED BECAUSE MY CURRENT BALANCE IS FAR DIFFERENT EVEN AFTER CERTAIN AMOUNT ADDED TO THE ACCOUNT
