Cannot Find Disney+ Activation Email

I just got billed for my Disney+ account and realized that I should not be getting billed any more with my DirecTV Premier package.

I went through my emails and cannot find the Activation email for Disney+.

Worse, the email address I use for DirecTV and Disney are one and the same. Not sure that should matter because from what I read it should not matter, but I thought I should mention it.
