Why can't I sign in on twitter?

[Leanne]

I've done nothing different on my account, and on my twitter app on blackberry and ipod it says I have 0 tweets, 0 followers and 0 following when each of those were 10,000+

On a web browser it says that my username/password is wrong when I'm 100% sure neither of them are

I've asked people to search me, some say I don't come up and a few are saying I do come up and I still have my right number of followers/following and tweets

I've reset my password incase it was someone that's hacked me but its still not letting me sign in?

Am I on some kind of limit or have I been reported or what? I've ran out of ideas idek
