Why am I still being charged for a closed credit card?

<p>I logged a complaint on Hello Peter in April this year. The reference number give to me was ********** 980. This was dealt with by Nkululeko Sithole from the Complaints Resolution Centre at Standard Bank. She confirmed that my credit card was closed, and a paid up letter was sent to me. I still received statements for an outstanding amout of R57.22. She confirmed via email that the statements were sent in error. To date which is now September, I am still getting those statements for the same amount except interest is now accruing on that amount. This morning I got a statement again and this time it mentions that now I am in bad debt and it has been sent off to collections? This is utter nonsense. I want this to be escalated immediately!</p> <p> </p> <p> </p>
