HELP! Got phone unlocked but want to go back to Sprint.

[banginbabe]

I am new to the developers forum but I'm praying that someone will be able to help me out. I went and paid a guy to unlock my Sprint Note 3 so that I could use it with T-Mobile but when I took the phone to T-Mobile they said it can't be activated because it's still under contract with Sprint. Now the guy that unlocked the phone knew it was under contract when he unlocked it and didn't say anything about it being a problem. I would really like to just undo what was done to my phone and stay with Sprint if possible. Can anyone help me? Thanks in advance for any and all help
