they scammed me and did not let me withdraw
Well, I suppose everyone is entitled to their opinion here. My opinion is that they didn't and that you're lying. But, of course, I have no evidence for that, just as you haven't show any evidence for your claim. So I guess, it's your word against mine. However, I tend to trust myself more than someone I'm seeing for the first time on a forum.

I think a lot of people will back you up and freebitco.in is one of the oldest and most legit crypto sites and they don't ban or don't pay without good and valid reasons. I have been using the sites for years and have not had any single issue.
