They called me twice today from 613- 209-7431 with the same robo computer generated voice uttering threats to prosecute the gullible me (but they didn't say my name) for committing federal criminal offense related to CRA tax evasion. These boiler room scammers tried their luck on me last week calling me from other numbers, which also were reported by public as scams. They use this same number to defraud people for at least a year now. Don't we have police force on duty to investigate such problems? Why these scammers are still in business?
