non closure of credit card account

Due to debit order amounts of over R3,000.00 per month and trying to get the bank to stop these amounts going through the account as I have no idea who they are I was at my fustration limit so on the 27th of January 2016 I phoned and requested the amount to close this card account and the lady at Card Division gave me an amount and the account number to pay it into and she assured me the account would be closed. Now today I am here at the Cradlestone branch with Paul Serobatse trying to get someone to help me to close the account as there is another amount due if over R6,000 rand that they want me to pay after I closed the account. Paul has been on the phone for almost three hours trying to resolve this and no one at Standard Bank will take responsibility for this.
