AIPRM just don’t have the resources, time, or inclination to become their own Credit Card Processor. If there is an issue with a card, and it is declined by Stripe or other third-party, then that payment doesn’t get through. Your bank should notify you of anything like this, and it should certainly show up on all of your billing and statements.
From the AIPRM side of this situation, you simply stopped payment and thus the service also stopped being renewed.
I cannot speak as to why your payment was declined by the third-party credit card processor, any more than I could know why you switched from an already accepted credit card to one that got rejected.
