I received two calls from this number.  I answered the first, but nobody said anything.  I called back and was told that the number was not in service.The second time I answered the person said he was calling me from the IT department of PC Doctor, and asked me if I had a computer.

As soon as I cleared my list of blocked numbers, these annoying calls started flooding in again.  Tiresome in the extreme, and no way to counteract as a call back gets only a horrible screeching fax-sound on the line.

Got a hang up message from this number. When I tried to call it back it said the number was not in service.

They call and left no message.  To me I'd go along with the phishing idea.

Hang up calls when message machine picks up.  This has happened on March 4, 2011 and March 7, 2011.  I have our number on the do not call list yet they still call my residence.  The company is unknown to me and I wish to report the caller so a penality can be handed out to them.
