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

I alerted 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. Virgin Money should refund these fees too.

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