Caller ID showed "Fort Collins, CO." Like most telemarketers nowadays, they said they're a non-profit called The Energy Conservation Alliance and are not selling anything...But if we qualify with one of their "partners," they may help pay for energy savings. I checked out they're website at www.EzToBegreen.org. Their testimonials make it sounds like they sell windows. How can they get away with being a non-profit?? Sounds like a scam. Blocked!!!
