Hello Bona Dea,
I would advise to contact the owner of the credit card and ask for assistance.
I myself sometimes struggle with entering the right information when paying via credit card.
There are different verification procedures depending on e.g., the country, card issuer, etc.
Good luck with the payment and taking the exam.
Kind regards,
Leandra
