Accidentally linked my friend's HBO Max account to my att account
I accidentally made my friend's HBO Max service provider my att wireless account. I wanted to unlink it and make my own HBO Max account for my family to use but cannot find a way to unlink the service provider on either end. I have looked through a lot of forums going through both HBO and att and they both claim you need to go through the other service to fix this issue. I cannot find anything in my att account settings to even see the HBO Max settings.
