claimed he was CRA and I owed them money

Claimed he was CRA-which I know is not correct
; they only communicate by mail - so I am no calling him back!! He seems to be blocking me.
He said CRA was coming to arrest me.

Got a call a couple of minutes ago from this number and the noise in the background so bad I couldn't hear what the man with an Indian accent was saying. So I hung up and called the number back. He said he was the Canadian Revenue Agency and that the CRA had filed a legal case against. me. I said I thought this was a scam and that I would call the CRA myself. He said "You do that but if you don't call back in ten minutes of time you will get arrested."

Received a call from Jason at 613-707-2827 claiming to be from CRA and that they had launched an investigation against me and my property.  Did not and will not call this number back as CRA will only initiate contact via correspondence and if they do call, they do not leave detailed messages on voicemail.
