WoW classic Where to find and agree to terms of service?

I have had my account for over 2 months, I’m lvl 60, people cannot send me mail because I have some sort of trial account and not a full account because I havn’t accepted the end user license agreement… I have looked EVERYWHERE and even submitted a ticket. they say it’s in my account management however it is no where to be found. I even changed regions and nothing. where is it? thank you
