Yes they are scammer coz you can't withdraw your money
I don't understand why you keep commenting against the consensus without any evidence . Maybe you have some kind of problem or you are using wrong method to withdraw.  So you cannot withdraw your money.  So you can't make negative comments against someone without any proof.  So it should be mentioned here what kind of problem you are facing while withdrawing your funds so that if you are trying in some wrong way then everyone can help you.
