Received call purportedly from ConEd. Wanted me to switch to a highly suspicious "cost saving" energy plan which had high cancellation fees. Refused to give me details in writing. Gave my wrong address, even though I've had this number for 8 years. As I asked more questions and said I was surprised he couldn't even send me to web site for more info. I suggested perhaps I should call 311.gov for info on this energy plan. He hung up.
