Deleting an online XBox Live profile to take the gamertag

Ethan - Feb 1, 2015 at 11:35 AM

I have two XBox Live profiles and wish to use only one on my Xbox. I have the second with a gamertag that I'd like to change to the first profile's tag which has virtually no "G" on it. I don't want to pay for changing the first profile's tag as I've already changed it before so I want to delete it altogether and thus make that tag available for my new profile. Please assist?
