By "they", I believe you mean FreeBitco, how did FreeBitco scam you by not allowing you to withdraw? It would be more helpful, or should I say that, you will be taken more seriously if you can post the details of what happened, and also how you came to the conclusion that you've been scammed, this you can do by providing evidence of your claim.

Without doing as suggest here, your comment is just another spam and will be treated as such by everyone, including the admin here.
