Ted here form Shopify, thanks for posting your query!
Our support can help reset your credit card attempts, but we would need to authenticate your account to do this which I can't complete on a public thread such as the Forum Community. When you have a moment, please contact our live chat, email or callback support here so we can authenticate your account and take a closer look into this with you.
Since this is the next step I’ve marked this reply as the solution for the benefit of others who may discover this topic.
If there is anything else I can help you with, please let me know, I’m happy to help!
