3 October 2012 -- 10:15 am -- Caller ID said "2532452041", same as the name that was displayed.  No message was left.

They left a 3 second blank message. Thanks to Caller ID I never answer these types of calls.

I have received several from this number.  I left a message.  I was immediately called back from a cell phone registered in Florida.  I asked him to please take my name off the calling list.  His reply was that he shouldn't have wasted his time calling me back if I wasn't interested in reducing my electric bill and that I should have stated this on my message (just left my name and number).  I said I've received several calls from his company and would just like to be taken off the list..  He then asked if I knew what one plus one was!!   I replied I think three!  He told me I was ignorant and hung up on me.

Robocall from a solar panel sales group.  I pressed one and got a recording, so I left a message of good luck and hoping the federal government would make them guests in a confined environment.  If you get the drift...
