I sent them an email 2 hours after this message:
Dear ni23457 (I'm talking to you here, because you are the most concerned of our clients), please turn to our customer support and confirm your dismissal of the KYC procedure. Your 100 BCH will be refunded to you right away, excluding the network fee.
I even promised these pieces of shit that I would not initiate problems for them in Russia. And what do you think? They did not return anything.
Good day to you!
We have received your last letter, and our support sent you a reply to your original ticket.
Please confirm that you are refusing to pass the KYC procedure and you will be refunded within 24 hours.
We have carefully saved all the information about your situation and will submit it to the legal authorities should they request for it.
To all our other users: don't worry. If you aren't trying to cheat and/or scam, you have nothing to be afraid of!
