Update webstore email

I have what feels to me like a very simple request.

My work is changing email domains, and I need to update the email I use for webstore as I will be losing access to the old email domain in a few weeks.

I have tried exhaustively to get help through the in-game chat and been completely unsuccessful.  Totally frustrated.

My Game Center ID is tied to my game (and allows me to access my account when I have changed devices in the past).  I have no issue accessing the game.  

I have been able to provide all my ally code, player ID, and related email addresses (can provide here upon request including screenshots from in game chat, but would prefer to do so in a DM and not public forum)…but so far, the in-game support has been totally unable to help me with this.  I’ve been trying since June 22nd…as of the time of this writing, it’s July 18th.  

Please let me know what info you need from me…driver license, MFA to email, blood and urine sample, first born child…I’ve got it all…literally just need to change my email address for webstore.
