Cannot reset password for blocked Apple ID

Dear Apple Support Team,

I hope you are doing well. I am contacting you because my Apple ID has been blocked, and I am unable to reset my password. When I try to recover my account, I receive the message: “Cannot reset password – This Apple Account is either not valid or not supported.”

This account is very important to me, and I would like your assistance in verifying my identity and unlocking it. Please let me know what steps I should take to recover my Apple ID.

Thank you for your help and understanding.
