I've had earlier Dropbox Plus from my institution, but I downgraded it to Dropbox Basic from 10/11/2025. How can I remove the card payment info from my account (I don't see any option to do it myself). I got message from card holder, that the card has been chargred on that day, but I have now info or receipt of that payment at my account's billing info. Is it still possible that the card would have been charged despite the plan cancellation? The description ID in the bill is [removed].
