Got called by this number twice...Saying she's Mrs Howard and needs to talk to me about charges on my National Grid bill. Gave me a phone number to call and a reference #. Said to have my electric bill with me when I call. DEFINITELY a scam. I'm reporting it to National Grid- these people are trying to get information from your bill so they can steal from you! If it was truly National Grid, they would already have the information on my bill.
