ABSA card division cannot reply to question

A debit that I consider ********** and misleading was charged against my Absa credit card. For some time I was unable to open my electronic card statements because Absa's Striata reader would not open it. By the time I got that problem sorted out with Absa, the debit had gone through and it appears I could do nothing about it. To prevent recurring future debits I cancelled that card, after paying the full outstanding amount. I was issued with a new card with a new number. I was told at the local branch that no recurring debits for the old card could be charged against the new card. I contacted Absa card division by email for confirmation but I cannot get a satisfactory reply from them. This whole matter has been going on for months (since March) without any progress being made. I am now frustrated to the point that I intend closing all my Absa accounts, personal and business, unless I can get a sensible reply from the card division.
