How do I find someone else who has Yahoo?

How can i find out who got into my yahoo email? my password has been changed by someone else.?

• i've emailed yahoo several times with no reply. only that i need to know my current password to change or cancel my account. does yahoo have a phone number for customer care. this a serious offense.

• Answer:

  if i were you, i would cancel your account and then make a new one because whoever changed your password is probably looking at your mail and using your account suscribing for things and that usually costs money.
