Where is the form to "complain" about something happening on 360?
I know how to change my settings, name, nickname, etc., however, for a few months now I've had problems changing my display name. When it finally does let me change it, it then takes a while (days, weeks, a month) to be able to change it back or to something else. I changed it again yesterday and now I can't change it to something else. This is really getting frustrating. Where can I write to complain about what's going on?
Thanks in advance for any help.
p.s. The more detailed help the better, since I can't really ask a lot of questions after I post this :).
