TWO FACTOR AUTHENTICATION Code not being sent to my email

I set up two factor Authentication for my two accounts a while ago. It was working yesterday but today when I tried to log on it asked for the code, but no code was sent to my email. I tried on both accounts, both no longer send emails to the account. Was my account stolen? Was there a issue with the email? I would like to take to staff but I'm not sure who to contact and I can't open a ticket because I can't get in game without my code. Any help with this issue would be great, thank you!
