I lived in Massachusetts (I now live in CA) where my electricity and gas/heating were provided by a company with the same name, NSTAR. I shut off my aqccount and told them I was moving, assuming that both accounts from the same company would be discontinued. My electricity wasn't and I received a bill today for almost $1200 for the apartment where I haven't lived in almost 2 years. Am I responsible for it? What steps should I take to make the current occupant pay for this?
