When Bungie Drops Halo Reach, Who do I PM to get Unbanned

I have had a couple of Instances when my friends have been banned by accident, Who would i be ablke to PM and get this sorte out.

I’d shoot bs angel a PM about this maybe. She’d know who to go to, if anyone. Be sure to be prepared, too: You’ll likely have to explain your case and prove your innocence.
