heres a few suggestions
Sort your Xbox app out
I created an account on you app which it allow you to do and then when I log out and tried login in again it would not let me.
so I tried setting up new account which it let me even let me purchase a server but low and behold as soon as I log off could not get back. Oh yeah you app allow me to purchase a server when you had none available for that game.
Here's abother tip sort out you website login's
Both accounts I created on app would not let me login to your website originally. Then it let me re-register one of my e-mails. Which I did coz how else am I supposed to put ticket in.
That's the other thing if your having problem logging in To website and or app how are you supposed to request help when help is all behind the login.
