have you opened a support ticket?

I thought I had, but apparently not. Now I have submitted a support ticket.

Here's the resolution to the whole thing.

1. Hello!
   Thank you for contacting us.
   
   There are two ways to activate the Raid Card for another account.
   Create a new Google Play account, since Android allows only one in-app subscription per user.
   Here is an instruction: https://bit.ly/1DAYhUr
2. Terminate your current subscription, wait until it expires, and purchase the Raid Card from the same Google Play account.

   I hope this information helped. 

I've cancelled it on my "old" account. But I'm not waiting another month before I activate it on the account I'm actively playing... I'm just not going to get it again. This shouldn't be this hard to fix.
