Ordinary service RCS

With regards to my Money Credit card, I made a payment into my card at the beginning of April and suddenly they send me a text saying the following :

MR Nundhlal, we apologise that your April RCS Credit Card statement referenced incorrect payment details for EFT & online payments. Correct Bank details are Bank Name: Mercantile, Br Code: 450805, Acc Type: Cheque, Acc Name: RCS Credit Card, Acc & Reference#: Unique number on back of card

I would need someone to rectify this asap as I am trying to use the card and unable to do so
