I paid for the connection and they didn't send anything. Before the payment, they answered all my questions, but after the payment, I've been completely ignored for several days! I wrote a complaint to freekassa, and immediately the seller black-voip responded and asked me to delete the complaint. I deleted the complaint, but he ignored me again, and now it's forbidden to add a second complaint. In short, black-voip is a scammer. Beware of him, work through forums or pay through guarantors!
