How do I stop cfnow.fans from repeatedly attempting to charge my Apple Pay virtual card?

I didn’t subscribe to app name cfnow.fans but somehow it has got my Apple Pay virtual card information and is constantly trying to charge 39.99 to it. Gets declined because I don’t have sufficient funds in it for it to fulfill charging amount. I changed Apple Cash card information but it’s still trying to charge that same card but now it says”declined incorrect card information.” How do I stop cfnow.fans from roaming in my wallet and trying to steal money out of my virtual card?
