I have also received calls from this number and I just don't answer. I have actually received 20 calls from them since March 3 until today March 18. They have called one or twice daily, and since the number is not familiar I don't pick up. I figure if they really want to speak with me, they can leave me a message. I tried calling the number and a recording comes on saying it is disconnected. My cell phone is not prepaid.
