I want my appropirate battle-tag back

The counselor GM Leybanath did’nt accurately understand of the problem
what I’m with now.

He/She/They(idk gender is) told me to go ‘support blizzard com help restrictions LINK’ but thers no ‘restrictions on your account’ just clean page was.
And there’s no page to how to get my battle-tag rollback.
(i dont wanna buy or use free battle tag changer, just want my whale#3986 back)

You bllizard guys forced me to change my battle-tag whale#3986 to GrayImp#35379 with e-mail (the reason my b-tag name ‘whale’ was Inappropriate nickname and i dont understand why) and i dont wanna report them who reported me about my battle-tag.

AND I USED THIS BATTLE TAG 10 YEARS MORE AND SINCE BATTLE-NET APP WAS CREATED.
I JUST WANT MY BATTLE-TAG whale#3986 BACK !!!

If u bllizard guys got better LINK to my problem, send me next, or call manager who can chat with in live-time in korean or english.

I just want my b-tag rollback not this one u guys randomly named to me.
