Name change problem

Hi, i got 2 teamwarfare account, one that i named DeadGod and the other is this one, the_death. I would like to get my Deadgod account remove and do a name change with this one because all my guid's are on this one. But i asked to get my DeadGod guid's remove and i can't acces my account anymore. So i don't know if you can help me.
SO i want to delete my deadgod account and change the name of my the_death account to DeadGod.

Thanks

I show you with three accounts.
the_death
deadgod
POWERED

The account deadgod has no GUID's on it, so I deleted it. The account POWERED has a lot of GUID's on it, you need to get it sorted so it can be deleted. You're only allowed one account for various reasons, one of which you can see.

hum the Powered account is not mine, i think it's my brother's account so i don't want it to be deleted. the_detah is my only account now, so thanks a lot.
