Now, I already contact to Nordeus Support Team via Khris link( I don't see any 'contact us' link in game).

How many days will it take to get an answer or get real help (normally)?
It is possible to continue playing game with this account as a guest? (May be I will connect it with my Google+ account later).
Will my FB profile be permanently deleted in game?
Thanks for all your helps
With Hope!
