DigitalOcean billing infinite loop edge case

I'm guessing that this is an edge case.

I'm posting this on HN so that product designers can take this edge case into account when designing payment processes, especially payments related to the exit ramp.

---------------------------

I delete my last droplet on DigitalOcean (DO) in mid-November 2022.

Coincidentally, my credit card on file also expires in Nov 2022.

Receive an email from DO on Dec 1 that my credit card was declined (there's a last remaining charge of $3.22).

I can't update my credit card on file (can't find it anywhere in the account settings).

Every time I click the "Pay Now" button, the page just refreshes and shows me the "Pay Now" button again.

So I open a support ticket. Attach screenshots. Receive an automated email that says reply back to get a human to email me. Reply back. Don't get any human. Notice that my support ticket no longer exists on the DO support site.

Create a new "Team" (Some new concept they created since I originally started using DO. Not sure what a "Team" is. But credit cards now need to be associated with "Teams".)

Now when I click "Pay Now", it takes me to the billing page for this new "Team" I created.

I make a $3.22 payment. DO thanks me for prepaying for future usage on droplets on this new "Team" I created. But I still owe them $3.22 for Nov 2022.

There's no way for me to get in touch with a real human to resolve this. Have opened another support ticket. Received the same automated email I received earlier. It says that if I reply to it, I'll have a human respond. Have replied to it asking for a human.
