They called and said they were with Eco Energy Services and would be on my street checking to see if homeowners are eligible for a rebate. The caller sounded Mexican. He said the visit would only take about 20 minutes. I was on my PC at the time of the call. When I asked him for their website so I could check them out, he gave me a website that didn't exist. (www.ehs.com). When I told him that I wasn't interested as the website he gave me didn't exist, he just said "bye" and hung up. I'm so sick and tired of these types of scammers calling!
