My account was locked, and I put fake info. They denied my thing.

my outlook account is locked i put a fake phone number so cant verify it and the info is fake so i forget it.  I talked to live chat and they wouldn't help, they told me to come here.  I can prove it's my account a few ways.  Please help me i don't want to talk with a support agent where everyone can see it?  The agent told me to do it here and refused to help so idfk who to talk to.
