Annual Payment not going through

I've had a pro account for over a year, but I forgot to update payment options when switching bank cards.

I would love to pay for an annual account, but I'm having an issue when doing so. When I plug in my card information, it has the appearance as though it has worked. My avatar is back, I have full access to the website, etc. But this only lasts for a day or so. I'll come back to play and my pro account has been stripped. I'll check the bank account and the order has not been processed or anything. This has happened 5 or 6 times. I'm mostly worried that all the charges will ring through at the same time and I'll get blasted with $120 in charges for Geoguessr subscriptions all at once. Also, I'd like to help in whatever way possible because I know this API issue is ridiculous, and I'd like to make sure I'm supporting this game. Thanks.
