Audio Clearance from 343i

Yo new to this forum and i have absolutely no idea where else to ask this type of question.

im a music producer from australia, and im releasing a drum and bass track through a music label.
In this track ive used an audio sample from halo 4, which is the didacts speech upon his first interaction with the Chief.
The track will be released for commercial use (i will be making profit from it) so obviously i need clearance/approval to use the audio from the original content creator (343i)

So my question is does anyone know how i can get in contact with someone from 343i to shed some light on this, there is a link below to the track to hear the samples i have used.

Thanks in advance
