Got this same call today, left a message & then I called back. The first man identified himself as Nate Leahy, saying I owed the CRA over 4 grand since 2011-2016 and if I didn't pay it I would be arreseted for 6 days and would have to go to court. Then I got directed to someone else who wanted me to be alone when we spoke. He couldn't seem to know how I got his number and be vice versa... Wanted to know if I had the funds to pay off my debt, when I said no, he then asked how much money I did have... By then I knew somerhing was up so I googled the number and found this site. Thank you so much!
I got two calls from this number that sound exactly the same as others have reported. Something about officer Greg, legal troubles, etc. Sounds like it must've been a recording talking through my voicemail message. Definitely going to ignore it.
Gotta love technology nowadays. I don't answer any calls outside of the country nowadays and allow calls to go to my voicemail. They did leave a voicemail saying the issue at hand is extremely time sensitive and if I don't call back then I'm on my own, "good bye and take care". Well no need to call back as it sounded like a scam.
