Pathetic service, thanks God I took my business away

Last month I visited the Capitec branch in Brackenfell to settle my credit card. I requested the consultant for the settlement amount which she confirmed and I paid it. In addition, I requested the closure of the account which she confirmed to have done it, and even tear my card. To my surprise, I'm getting an email from Capitec demanding me to pay the credit card. That is unacceptable.
