E-mailing Record Labels

As mentioned (quite a while ago now) I sent an e-mail to three different record labels in hope that they would let me use their song in my video. I sent an e-mail to Parlophone, Polydor and Creation Records. Since I decided that the song I am going to use was F.E.A.R. by Ian Brown, I only needed to hear from Polydor. Sadly, I have not heard from Polydor, and since I have started filming, I may have to use the music, regardless whether they say yes or no.
