Someone hacked into my account and the only way to rectify is to call them. I can't email because the email & phone number has also been changed. Twitter hates human contact because the number they provided will not allow a person to speak with them. I could log out of my account but then I won't be able to get back in. Twitter has to have a way for users like me to get help. E-mailing assistance to your e-mail address or sending a code to your phone number when neither can be accessed because it's not known is a joke. HELP!
