This number is a scam - i KNOW for a fact i do not owe anything. First of all - i keep very very tight hold of my credit, have gotten a refund from the government every year, my work covers my mspo plus I called them and they said my account was clear. i have one credit card that has no balance, i have students loans in repayment.
this is a scam and i feel bad for anyone they are harassing that has debt and falls for whatever scam this is. Everytime they pretend I owe somethign and I tell them no i do not i talked to CRA last time you called from a different number - it stops for awhile, then it continues form a different number in a few weeks.

Phone numbers get recycled all the time.They recycle phone numbers after 3 months, so many people could have had your phone number before.Don't worry about it.

Unknown caller.  Doesn't leave message.

they been calling my house everyday in the mornings then in the afternoons never left a message then i answered the phone and said stop calling here and hung up then 2 days later they call again and left a message for my boyfriend stating who they are why there calling saying he owe canada revenew and there trying to collect to call them back funny is thing he dont owe the gov anything

I had this # call me all day as well.  Claiming a debt I have with the province. I have no clue how they got my phone # as my phone in new and unlisted. They tried verifying who I am. I refused to give my address as I need verification of who they are. Their answer to that was they would put revenu services on the line. Really? Sounds fishy to me.

what kind of a cheap bunch of
wanna be outfit would carry on
solicitations on a sunday at two in the afternoon
your bosses must be real proud of you
next time leave a message or say something
instead of hanging up
grow some stones if you can bloodclot

They are collection company that buys debts from the goverment. THEY ARE NOT PART OF THE GOVERMENT!! Any collection agency is only allowed by law to contact you once a month, any more then that is harassment! The debt is allso only good for 7 years from the time they bought itfrom whomever sold them the debt in court. Basiclly these debts get bid on in a sort of auction through court. After 7 years by law they can not collect anything thanks to the statute of limitations law. FYI and pass it on.
