I have to laugh at these imbeciles.  Calling from a huge call center.  All I hear is "hello, hello, hello....."

SCAM. They are looking for you to give them account info saying that they can offer savings to your National Grid account. They called my business. We do not have National Grid. They are not a legitimate company, they want to steal your identifying information and steal you $$$. I have contacted the authorities. Do not give them any info. Caller ID places them in Adams MA but who knows
