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.
Had my FreeBitco account registered in 2015 I suppose, that was before I even joined this forum, how I discovered the platform was through a Google search I did on how to earn Bitcoin for free, so in my quest to earn free bitcoin, I stumbled on this legendary platform, and since 2015 till date, I have never had any issues what so ever, I've never contacted a customer care for any reason, and even though in the course of the years, I've had breaks, some long, some short, funds on my account have always been met as I left it, and withdrawals have always been processes timely..
Can there be any one who actually have a bad review of FreeBitco? I think none.
