***** on credit card not refunded after 3 months

I alerted Absa (via Virgin Money) of ***** on my credit card. However, after several weeks of emails only some of the amounts have been refunded. The card has been cut up but I'm not secure paying off the outstanding amount, which is a ********** amount that should be charged-back or refunded, and have therefore been charged significant finance fees. These should be refunded too.

Surprisingly, I've also not received information about a replacement card
