Unable to remove the last credit card from free vercel account

Hi support.
i was a v0 account and i cancel it . it should be applied on November 6, 2025

“Your plan’s cancellation is scheduled for November 6, 2025”

even though I cancelled it the credit card area says:
“You cannot remove your last payment method, because you have a v0 subscription”
It does not let me remove my credit card. and it put me in panic
