twice payment

on the 25 march 2015 i went to standard bank to close the old cheque account, new account was opened and the consultant linked the old cheque card on the new account. during april when i used the card to swipe it declined and i had to pay cash. in may i did not use the card but i received massages everyday says i swipe my card, investigation were done and i was told that those payments were for april even if i told them that early may i went to standard bank to report the card and i was told that it should declined because the card was on closed status that where they issue me with the debit card. even now there is not respond from them i'm thinking of living the bank
