Free Tier to PAYG upgrade stuck in progress and Support Chat fails

Hello Oracle OCI Team,

I am experiencing a very similar issue with my OCI Free Tier account.

I requested an upgrade from Free Tier to Pay As You Go. The upgrade process reached the following status:

"Your upgrade is in progress. You will receive an email confirmation when your upgrade is completed."

However, the upgrade never completes. My account still shows:

Plan Type: Free Tier

I have not received the confirmation email.

I have also tried to contact OCI Cloud Support through Live Chat, but the chat fails with:

"An unexpected error has occurred. Please try again later."

The OCI Help system directs me to Cloud Support Chat, but that support channel is also failing.
