This number called my phone and didn't leave a message. It's a local number so, I assumed it was someone I might have given my number to. I called back and it does 3 beeps and hangs up.

CRIMINAL PHONE PHISHING SCAM - Appears they may target elderly homeowners.

Their goal is to get you to let their "Energy Auditor" into your home. To do that they want you to call 1-800-837-1239.

Probably they will then either rob you on the spot, or case the home for a future burglary.

I am so tired of them calling my cell.  I have a prepaid phone so it costs me whenever I answer.  The problem is they have called me from different numbers.  When I did return the call to the 800 number listed above, they were girls talking about what pajamas they wore.  The whole thing makes no sense.

I got tired of their constant calls and finally pressed 1 to speak with someone. A guy named Greg answered and was quite nice about the whole thing. Still had the "this is a government program and we've already been paid" baloney they spout, but he verified my information and noted that "someone" had tried to remove my number, but that he would "definitely" take care of it. We'll see...

You have 2 problems here. This is not one entity but two. The phone number 904-874-8427 originates from that infamous phone exchange out on the beaches in Jacksonville. However they are acting on behalf of another bunch of shifty people in Orlando. They are the Organization for Energy Savings. They also use (904) 422-1000 & (904) 236-9439. These numbers usually show up as Cell phones but they are not. Also They have used deceptive names at times for their caller ID's. For instance: Vu Phu,,  Louis A,,  Moreno Luis. Both of these operations are highly suspect and both have been reported numerous times. My guess is that The phone bank is just a bunch [***] who dont know and dont want to know. The other bunch may be real crimminals. I have seen many accusations that they target old people and have used access to these people to case their homes and Neighborhoods. Dont know if its true or not but somethings stinks somewhere.
