How do i find out who previously had my cell phone number?

[sam's_a_star]

Ok im seriously irritated now, there is a woman who just called me (2am) talking about she had my number and was trying to see who called her! How do I find out what her phone number is? currently I know her first name! I'm seriously about to file a report against this lady because she calls me everyday!

(No stupid remarks please.)
