I receive a call from this number also...didn't answer, but after it kept calling I decided to call the number back. It is an automated system and it stated upon answering, if you want to be placed on a do-not-call lost press 1 and that's what I did.
Called my cell number. I no longer answer any number not in my addressbook due to all the unwanted calls I get. Sure wish there was some way to stop these butt holes from calling.
