Can someone hack my account back?

[I love ice cream!]

Its been over a week that I havent been on my twitter because someone hacked it. The hacker changed the email, password and username. I had about 3,540 followers and over 16 verified accounts following me. Is thier anyway I can change the email on it without signing in? Send links, and all the info you can. Also if you are a hacker can you hack my account and change my email back? PLEASE! I have tried contacting twitter but they wont reply its been over a week. I tried twitter support to, but it wouldnt help my problem. The username is @OhWhatATeenLife and I am surrently using @CanadianJDBiebs since my account was hacked.
