Cancellation/closing of credit card

I visited the Centurion branch of Standard Bank on the 24th of November to settle an outstanding amount on my credit card and cancel/close my account. I was informed that the amount cannot be settled inside the branch and that I had to do an EFT, because they only accept Standard Bank cards. I made the payment and sent the proof to Yogi Reddy (the consultant that assisted me) that same day. He rep**** and said he will begin the closing process. I received no further word back. I tried phoning the card division but once the verification needs to be done, they dont want to accept my pin for the card and therefore I cannot continue. I emailed Yogi about 4 times to follow up. I tried logging into my internet banking and couldn't, so i assumed the account was closed. Since then I have received a statement for the account with amounts outstanding. So my account wasnt closed. I lodged a complaint, received a ref number. But no word back. I posted on facebook, they asked for my number, but no one has phoned me. My credit record now shows bad payment and I cannot apply for anything. I found this out yesterday. I am fed up with bad service and no responses to my queries!!!
