Its no misuse, rather utilization of service to full extent. We pay them a lot already in montly bills. This is their way of giving back. I see no harm if people wanna utilize the service. Why people make everything complicated when it should have been simple. With calling cards, my calls would not always ring; now with direct call, i can stay in touch with my family easily and with less hassle. Its a win win. Nobody is losing; so why make a big fuss!
