(602) 639-4744

This number calls me about once a week. This morning it was around 8:30 am  It says UNLISTED on it. I don't like answering because I figure then they know they got someone a the number. The answering ma****e comes on but no message. I put it in search it comes back to P***nix/.Tempe AZ and says it's a cell phone. So the 800-number searches don't have anything for it.  Does anyone know if any of those searches that say they can find the owners of cell phones and unlisted numbers (for $$$) really work, or are they a rip off?   I should be able to find the number of someone who keeps calling me without paying for it. I wonder if my phone company would know (I have a landline) It also seems odd if it's a cell phone it doesn't say "wireless caller" or so****ing but says UNLISTED.
