Standard Bank Credit Card department

On the 2nd of March I went to the Benoni Branch spoke to the Credit Card division about settling my account, I was given a figure to pay and follow up with them on Monday to get a settlement confirmation which I did, I made the payment and on Monday I phoned and I transferred to the Retention division I spoke to Deven Lee Abraham's who tried to convinced me not to close the account but I told him I have no need for this account anymore and must be closed, he assured me its closed and I will be send a confirmation letter by e-mail, he confirmed my e-mail and all other details, a week later I have not received anything from him on the 12 of March I phoned again I spoke to Herman Morifi who confirmed that my account was still not closed and it has accumulated interests which I must pay, I told him my vision of the story and he said his going to escalate this matter to management I should expert a call in a day, today its the 18 of march I have not heard anything from Standard Bank and I requested my recording of the day I spoke to Deven and I have not received that as well...Iam highly disappointed and I feel very disrespected by Standard Bank and I will make sure I have them reported if they think they will be getting another cent from me
