I have replied to your PM :)
Our CS Support stated:
"Ask him to resubmit his ticket but instead of zero in Payment amount use any valid number. According to CIS it happens sometimes when invalid value is used in one of the required fields"

As I mentioned to you in our PM, we're actively trying to discover and resolve this technical bug we have within the system. We're working with the ticketing department in Minsk to resolve it.
I have a few more details for you but I'll converse them to you via PM again.
We of course appreciate your loyalty and commitment to the game, as well as bringing this issue to us, and we are trying to get it resolved.
