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.

They're calling me too.  I have never made enough money to owe the government anything.  Wtf

I get them too....i also never ever answer a number that i dont recognise...they've never left me a message to explain who it is?

Its ARC, a collection agency for MSP.Don't worry, MSP cannot go on your credit report.

i am about to call revenue services and get them to cease and desist collections actions against me because according to my calculation based of revenue canada income tax returns since 2008 b.c. govt owes me for overbilling on my msp

They called me today.. thanks for the heads up!
