Has this ever happened to anyone else??? Twitter problems!! HELP! ?

[Christina]

So my twitter won't let me log in and I am 100% sure that my username and password are correct!! I have tried logging in on safari, deleting the app getting it again and resetting my password (this ends in it taking me to the sign up page for a NEW twitter I don't want that.) when I try to log in it says: Error. Your username and password could not be authenticated. Double check that you entered them correctly and try again. I have tried calling twitter itself and it will not let you contact them from the phone I do not know the email. Can anyone please help me?! Thank you SO much in advance!! <3
