I purchased a used verizon iphone 4s from a friend and set up the device last night on verizon's bring your own device plan. It has been over 16 hours and the phone is still not working. When I try to make a call, it brings me to the national payment center. When I set the phone up last night, I also signed up for the auto pay, so I'm not sure what the issue is. I cannot reach a person on the phone as the phone will not dial!
