OpenAI Downgraded my Pro Account to Free account?

I’ve been a PRO member since Oct - December 2024, and today at the payment day of my subscription OpenAI payment system suddenly (didn’t renew or ..) cancelled my subscription and downgraded me to a Free account today ???

So suddenly my responses are free-account-restricted and I’m being asked to pay for subscriptions again.

Why is openai cancelling subscriptions ? Anyone else experiencing the same thing?
