Has anyone had someone knocking on their door asking for your AC

Upper Township - Has anyone had someone knocking on their door asking for your AC electric bill recently? Claiming they can save you money by getting rid of the supply charge? A white van with Delaware license plate. Two younger men, one caucasian and one African American knocking door to door. I called AC electric right after and had this company blocked. AC electric say they are seeing an overwhelming amount of people in the same situation. They are legitimate companies but renewable energy startups. What they don't tell you is that, these companies can raise the rates anytime. Please be careful of this scam
