Threatening call by someone with a think indian accent

This is the second time I have recieved a hang-up call from this phone number.

harasses and makes violent threats on a repeated basis

every time i pick up and answer they hang up... but when i call back it says if you want to b placed on the do not call list, press one. it said that calls will seize after 3 days... ITS BEEN 6 DAYS and i'm still getting calls. i want to go to billings Montana with a couple of grenades and let them know how i feel.. ( i won't though because i don't have any, and its too far away)

Please be advised that this is not Scotiabank... its a scam to obtain personal information on individuals on "behalf" of Scotiabank trying to sell insurance. ITS FRAUD

The person said its a private number but the phone number was visible on the screen. When I asked who it was they hungup. When I called that number they kept quiet and hungup. Later that night when I called the number it said circuit/channel not available
