"Unauthorized halo user"

Anybody know what this means? Get this message every time I try to play online? Campaign is literally the only thing that works, please help.

Try an uninstall/reinstall. Thats the only thing I can think of

Yeah that’s the first thing I thought of, didn’t work though.

Have you tried calling support?

Where can I get the phone number?

Does anybody from 343i actually want to help with this? A refund or actually getting some technical support would be nice.
