Show a little bit patience, your withdrawal requests aren't even 48 hours old. Looks like they are doing an investigation on your account. You should have waited for the final statement of their email support before creating this accusation. They do have a telegram channel and the admin is active there. I have already informed them about your complaint on the telegram channel.
Leetbit has an ANN thread on Bitcointalk forum. OP has already made a post in their ANN thread before creating this accusation.
Hello,
I really appreciate your help.
And you are right, I could have waited longer for an official statement, but locking my account and not providing a reason right after that seems shady and scary to me, in my opinion.
My Regards.
