Yeah I just got an email with that number in it as well as this contact information:
Section Attorney: Jack cooper
Address: Peter J Leveroni Law
45 Braintree Hill Park
Braintree, MA
Zip- 02184
I haven't called it yet but good thing I looked the number up, looks like I'll just have to ignore it, lol. :)
You can probably simply call your local city's FBI office and tell them that you are getting calls from people with indian accents claiming to be from the attorney generals office.
Probably won't stop them, but it may slow them down until they get caught.
Typically though at least in usa, those in state attorney generals offices are actually the people to talk to. They probably won't take kindly to others impersonating
