This is national grid. It is the same number that called me in the past when my bill was overdue. That wasn't a scam; my bill really was overdue. But I still didn't pay it by phone, I simply paid it electronically the way I pay all my bills, once I had the money to do so.
Currently, they are calling to schedule replacing my meter free of charge. This is because Mass state law requires the replacement every 7 years, even if the meter is fully functional. I converted from oil to gas seven years ago. Scam? No, not in my case.
But I'm glad so many others are suspicious in general. That is a healthy skepticism. For me, it checks out in this case.
This is National Grid. They say they want to change your gas meter and when you make an appointment they do not come. They threatened me with the sheriff unless I responded, set up the appointment and waited all day. No one came.
I got a call from them, didnt pick up, they left a message on my voicemail (they just said "..calling for an important matter, please call us back..." I live in CA, had to get a new cell phone number in NY years ago and I was living there in a hotel for a month, so obviously didnt have an account with them. No idea how they got my number but anyway this is must be scam.
I have been receiving several calls from the 718. It is National Grid. they change meters every 7 years (not sure why). I too won't be calling them back especially when all I get is the last quarter of the message. The meter is in the basement not the apartment, just go change it and leave me alone.
