I didn't answer this call, the message left on my voicemail is clearly a recording because it starts part-way through the spiel; a guy with an East Indian accent says "... it is extremely time sensitive, my name is Officer Peter Sampson and the hotline number to my division is 437-888-3167, I'll repeat it's 437-888-3167, so now if you don't return the call or I don't hear from your attorney either then the only thing I can do is to wish you good luck as the situation badly enfolds on you, good bye."

Apparently 437 is a new Toronto, ON area code effective sometime in 2013.
There are so many red flags on this one it isn't funny.
SCAM.

I got the same message as "Pissed off." I called them back, they are diffinitely with Indian accent. I gave them fake info, they said I had miscalculations in my 2009-2013 tax returns. Anyhow finally they hang up on me. People should call them back to tie up their phone lines and time.

I called the number back and a different accent/voice message to leave a message "the person you are calling is unavailable, please leave a message".  Must be a scam or something?

I received a message today from Officer Sampson and promptly reported it to Toronto Police Services. Maybe, someday, someone will catch up to these thieves.

Also received "officer sampson"  spiel.  Very annoying,  luckily this was so obviously fake, but still such a waste of time. Starting to get  these more than necessary, just a different number, different officer.  Just be wary!!
