They keep calling me as well.  I told them politely yesterday to be removed from their call list.  I think these are the same guys who were formerly Skytel, Globus, etc.  This time my ID said "Out of Area." Last week, this number read as Skytel and a woman called about my Con Ed bill.  When I asked if she was a representative from Con Ed she changed her tune and said, "Um, no, um, we're calling about your Citibank account."  So I asked her, "So, which one is it?  Con Ed or Citibank?  Very different, don't you think?"  She hung up the phone.

Forgot to mention they said they were with "Empower" this time around.

Its been a couple of weeks since I received a call from the number. Originally they were listed as Skytel Paging. Now they are listed as Mpower  Energy.
This is a obvious scam if they are using ConEd as a part of their gimmick when calling areas not served by them.

Called on 5-31-2013 and didn't leave a message. Annoying.

Called 5/31/13 at 6:45 p.m.  I did not pick up and no message was left.  Caller ID read Mpower Energy.  Business call on a Friday night after 5 just didn't seem legit.  Glad I did not pick up.
