Keeps calling me, i pick up no one is there, i call back and leave a message but it just keeps calling me. and no one ever answers

Ditto ... the caller hung up.

They claim to be comcast, and ask for me by name. If they are told I am unavailable, they just hang up. If nobody answers, they dont leave a message. I am a comcast customer, so I called them to find out what they want....and they claim it is not them. what does one do in this situation

These people are WAY WAY WAY BEYOND RUDE. In economic times such as these the kind of verbal abuse they dish out is mind boggling!! If you just received a call but haven't spoken to them yet, be prepared these people are V-I-C-I-O-U-S. And it is in your best interest to return the call or they'll call your family, job, anyone they can link to you telling all of them that they are a collection agency collecting a debt that you are responsible for. Like I said...RUDE AND VICIOUS!!

Called at first at 9:35 am for 3 days straight. Now just called me at 12:44pm. I answered, they hung up. I called back it just rang and rang and rang... Called again, mailbox full.

this number is a cell number that is with western wireless corporation. for a small fee his name and address are avaiable. He called from a rural location of 23rd ave ne at the end of this road just off of highway 52. I did a sattelite search on this number
