This is a reoccurring call from a “UNKNOWN UTILITY SCAMMER."
According to my research program such as this caller is unlikely because government do not “advertise their services by calling or emailing people randomly or knocking on doors. If you get a message about an energy **sistance program, don’t sign up for it or give out any personal information. Instead, visit Benefits.gov to search for legitimate energy **sistance programs in your state. You can also check out your utility company’s website to see if it offers any programs to help you with your bills.
