My account was compromised and I guess a lot of e-mail were sent from it. The account is currently blocked and I can't get access to it until I verify it with an e-mail to another account. The problem is that the only account listed is an old university e-mail address that I can't access any more. I've tried e-mailing Microsoft and never get a response. Does anyone have a phone number where I can call to resolve this?

Thanks for your help.
