Yes, it is likely to be as you say.
It is said that CEX.io is against withdraw and deposit to a gambling site. Have you tried to withdraw to a noncustodial wallet first? Then you can send the money from noncustodial wallet to Freebitco instead which would be better. Or you tried that and it failed too?
I tried to withdraw on Coinbase too but the withdrawal was refused. In addition, support asked me to verify that the FreeBitco.in address was really mine, so I don't think that's the problem.
Another is that you should know if the exchange you are using is actually Cex.io, hope not a fake one with different URL? You have already posted the URL here and you are correct, but try and check that again.
Absolutely the URL is correct.
Hope you contacted their official account on this forum as I said above?
Yes, I contacted him yesterday.
Anyway they told me I would hear from them, but I don't understand why as I am verified and am just trying to transfer Bitcoins.
