It sucks that you experienced whatever happened in the game. I'm pretty sure bungie has a reporting link you can send your proof to somewhere on the site, I'd say where but I've never done it. So I'll look and see if I can find it. The only other thing is to report them on whatever console you play on. Edit: Here's the link to the help post to report to Bungie's help email. Though I would imagine their network guys are probably quite busy with checking reports and looking over their code to tweak things. https://www.bungie.net/mobi/en/about/Article?id=11929
