You have to be careful to avoid being scammed. Just first check with BC.GAME support page or try to log in to your account directly from your webpage before you act. I would have provided you with more details if you provided more information. Be it as it may, it's good that you are careful of antics on the internet, if it's just a direct email, it might not be from the company. I'd received lots of it, particularly the ones pretending to be from Coinbase, I always ignore them as the sender's email is not always that of Coinbase itself.

Just try to know the truth, and if they block the account truly, you can report it here: https://bitcointalk.org/index.php?board=83.0
