(800) 906-6574

I received a phone call from 800-906-6574 said National Grid did not received any payment from me, my service is going to be disconnected if i dont make the payment today. and they advised me to go to CVS, 7-11, or Cumberland Farm to purchase a money pak and give them the number over the phone. when I call national Grid and they told me that they are not aware of anything like this and they advised me to call the local police to report this scam.
