Alias Issue

Alias Issue

I just upgraded my account to handle 2 domains. I previously had 2 free accounts to house each domain. 

However, my previous "master" user email ( Bobby@enpointe.tv) is claiming to still be "in use" when I try to add it to my current account as an alias. I've deleted the old organization and the account. Though, I can still log into that email address which is still collecting email even though the Org it was created under was deleted. 

Please advise!!
