Listen to these answers about changing your password ! That usually does the trick ! It's happened to me and the Yahoo people told me to do that ! They can have your e-mail address , but can't do much with it if you change the password ! Worse case scenario : Change your e-mail address and tell all your VIP's the new one !
Either delete the account and make a new account-send the email to all your friends! Or you could find out some how to change the password to a password that no one could figure out, such as, afg596fhg. Ya, something like that. Hope this helps! Follow me!
