The technical support service is just terrible. It's impossible to get through by phone, they don't respond on Telegram, and they reply to emails with delays: you have to wait for a response, and if you don't manage to catch them in time, you get a status of "Resolved." They don't provide complete information on inquiries. I've been trying to change the installation address of the cash register for a month. Perhaps it's worth introducing tax liability for such organizations, which currently only threatens the owner of the cash register; then maybe they will start to take action.
