who is this?

Keep getting calls at late hours and want it stopped.

Called at 8;45 pm  tonight 2-22-10. They call all hours of the day. Have answered the phone from this # before and they hang up on me when I answer. Have them on # block but they still call. Who are they and how do you get them to stop. On the mo and the nat. do not call list.

Received unwanted call from this number identified as Private Caller. WTF?

Calls all days of week and sporadic times. Usually hangs up when answering and when you call back, no response. I picked up today and the caller asked for my husband. I said he wasn't available and to please remove us from his calling list. He got an attitude and said, "Who is this?" I responded by saying, "You called my house, who are you?" He proceeded to tell me that apparently I knew who it was since I thought I was on a list and I sarcastically replied, "Let's start over again. My husband is not available, may I ask who's calling." He said, "No, nevermind." So I called him a name and hung up on him. If anyone knows, please advise b/c I'd like to report the harrassment.
