how do i get rid of second classic gamertag

you can't, it's there for backwards compatibility purposes

At some point when you did change it, you changed your current gamertag but not the classic gamertag so it's kept the Rrey99 as your classic. There really isn't a way to get rid of it, you would just have to change it if the system shows the option when you change your tag.

Clearly you didn’t read what I typed. I have the Gamertag as my classic tag because I wasn’t able to put it as my top Gamertag without it giving me #’s, but when I put it as my classic Gamertag it worked perfectly fine. Then when I go to fix it and get rid of the #’s it lets me but doesn’t go though and gives me an error message.

So you said I can change my classic gamertag. How do I change that after already changing my gamertag or do I have to change my entire gamertag again to change the classic one?

Hi David,

The Xbox Gamertag FAQ from Microsoft support's page states:
"Q: I have more than 12 characters in my gamertag! Do I need to change it?
"A: Nope. If you like your gamertag the way it is, you keep it."

Well, I like my gamertag the way my classic gamertag is. Why am I forced to change it for the modern gamertag?

Re: My statement about cloning or duplicating:
I dont want to clone or duplicate a gamertag from one account to another. I want to clone or duplicate the name that already exists in my classic gamertag to my modern gamertag.

There HAS to exist an employee at Microsoft that is able to manage account details from the backend. How do I get in contact with them to resolve this issue?

"However, you can choose not to use or display the modern gamertag and primarily use your classic gamertag instead."
Great. How?
