Struggle to cancel credit cards

Hi<br> <br> I have settled both my and my husband Standard Bank Credit Cards. However it still reflects on internet banking and my debit order was even debited even though I don't owe a cent. We have been to the bank three times each and spent hours on the phone, why is standard bank so ***********??? <br> <br> When people owe you money you quickly respond but when one tries to cancel you even deduct money AND keep the cards open. WTH
