Energy Audit ...annoying

Same group of thieves trying to get you to let their sales person come to your house so they can sell you worthless items for super inflated prices.  They ignore all requests to stop calling.  They call using a different number almost daily.  They use dialers.  They call daily on both my cell phones and home number.  I report it daily to the do not call registry.  Nothing seems to help.

They have called everyday for a week. Pressed 1 and talked to operator asked them to stop calling and was hung up on.  Definitely a unprofessional organization.

This number has called repeatedly and provides an automated message on my cellphone.

Number is for an energy audit that will attempt to sell you services, the name of the Company is Organization for Energy Savings but I have been unable to locate further information.  They currently use 7 different 904 numbers that I have been able to identify.  The refuse to take you off of their calling list.
