Just got one of these calls - when I returned the call and started asking questions he said I was wasting his time and he had to take other calls. CRA does not conduct themselves this way...they send letters and have more professionalism on the phone.
Break on through to the other side and give Jim a call. See if he can maybe sing a song over the phone for you. While you're at it, see if you ever hear from Jim again if you don't allow messages from unknown caller. People are strange when you're a stranger.
Just got a message from this number. James Morrison ... Sorry officer James Morrison said that I shouldn't even try to disregard this message and if I didn't call back right away or if he doesn't hear from my attorney, that he wishes me "good luck" because they were pursuing this. Whatever "this" is. He was apparently talking before the message started to record so I missed that part. I could hear a call center background noise too. Thank goodness for sites like this so we can warn each other about scammers.
