Have you contact with the LEETBIT.IO support? Or they have any response about it ? You may should ask them why your account has been locked,
After that if you don't get any response they you can create a Scam Accusations against them with the proper proved and details in this board -
https://bitcointalk.org/index.php?board=83.0Yes I've contacted their support but they still didn't give me a reason for the account lock.
I just created a scam accusation which will contain further updates on this case.
Thanks
