My Outlook Account Blocked Due to Suspicious Activity, Unable to Access Xbox Account

My Outlook account was blocked due to suspicious activity, and I was prompted to verify it. However, I can’t receive the verification code because my phone number has changed. This account is linked to my Xbox profile, and now I’m locked out of both. I tried filling out the account recovery form, providing all the requested details (Skype, recent emails, Xbox username, ID info), but the response is always that my information is insufficient. The form seems to be reviewed automatically without proper checks. I’ve tried contacting Microsoft support via phone, but no one picks up, and I can’t access their community or live support either. I urgently need assistance to restore access to my Xbox account. Please help!
