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.
