How can I stop one website from trying to charge me through Apple Pay?

In regards to contacting the company billing.

I have contacted the company that is billing, but seems to be a third-party billing on behalf of someone else. They will get the scores no information unless I give them the first six and the last four numbers of that account trying to be billed, which would be the card? I have set up on Apple Pay. I have change the card with my bank, but since it is through Apple Pay, it just keeps getting billed.

I understand this but without being able to get any info out of the billing company website, I am giving them more personally detail of my card number. I don’t know how to get it to stop. And that is what I’m trying to find out. They are on an unsecured server and want the first six and last four numbers of the card which isn’t even the card number they have I believe since it’s through Apple.pay which I believe if I am understanding correctly because it’s a different number for the card registered?

so again, I’m trying to find out what I can do without having to give this website more info or having to freeze my bank account once again. Do I just not use Apple Pay anymore ever? I am at a loss.
