I have been trying to pay my bills but its keeps telling me my SIM cared is not registered. I tried calling in this morning and still receiving the same message. How do I make my bill payment without going to the kiosk? This is highly annoying. You guys don't give no warning, just go ahead and disconnect service, one day after it was due. Seriously, other companies at least gives 2-3 days grace period, or you can call in to make partial payments, there is no such service with you guys.
