Who called from 5127709042

Another caller that hangs up as soon as I answer phone. Don't they realize how difficult it is to get to the phone? Have people gotten this mean?

Got a call from this number saying it was "North American Energy Advisors".  Very suspect.

Called our office and hung up, then called back immediately. Caller ID listed the number twice. Some sort of energy reseller.

Called several times again today, wanting to talk to the owner. Would not leave a message, said they would call back. I think they're going on the blacklist!

Received a harassing call from "Kelly" at this number.  Apparently they are "North American Energy" and refuse to take us off the calling list.
