Who is this from?

Calling to leave voicemails about a "free energy audit" scam. Part of the same group that has been spamming me for months. Keep reporting them to https://www.donotcall.gov/, especially if you are on the list (which they do not respect)

I received calls from this number. my iphone will not block numbersI.so i list this & other unwanted numbers in my iphone as do not answer. so when thay call it comes up as do not answer.

I receive many calls from this number and others from the same company on my pay as you go cell phone.  I finally pressed  "1" and spoke with an operator asking that they remove me from their phone list but all I got in return was a sales talk; he would  not agree to remove me from their list.  When I insisted, he just laughed at me.

Energy efficient telemarketer saying I was revered by a friend and to call and set up and appointment. These people call me from 20 different numbers for the same thing! Just hang up or don't answer!!!
