Account Email Got Deactivated/Deleted Randomly

I cannot log into my other Blizzard account because I keep getting the message “Account Not Found”. I was just playing on this account the other day. I’m not entirely sure what the problem is, but from what I found I believe my Blizzard account got deleted/deactivated? I’m just not sure why it was? Wasn’t doing anything bad or anything like that on it. It just got randomly deleted and now I can’t log in. When I go to the support page for Blizzard, and put my email in, it says "The email address (Email Address) does not match any known Blizzard account. Please try another email address or select “I don’t know my Blizzard account email”. Please, assistance would be greatly appreciated. :)))
