just received 5 calls from an unknown number, finally I picked up and the person said to hold on. I then hung up. The person called back and I told them to leave me alone. They called back a 3rd time and I told them they were harrassing me because I didn't know who was calling me. She tried talking over me but I hung up again. They proceeded to call me from this phone number I listened till it said the call was being recorded and then hung up again.
My friend called from here because he's in prison, at first i didnt pick up because i didnt know who it was but they kept calling until i heard a voice recording saying it was him and to pick up because the first call was free. I got to talk to him 15mins for free.
