FRAUD - REPORT TO POLICE!!

Just got a call from the "CRA" with Indian voices in the background.  Apparently I didn't file my 2011-12 taxes properly.  Play with them and got them angry so that they hung up on my.  They asked for my cell phone number but I asked them to tell me which phone number they had listed in my file.  Then he said that he would call from the 1-800 # but got him upset when I told him that I didn't have caller ID to verify where he was calling from.  They threated me that the RCMP will be at my door in 45 minutes at the end of the call.

I received a call from these Lunkheads. I  said "Good afternooooon Scammers, how is the scamming goin today?" The guy sounded mad and said "this is not a Joke you failed to fill out your tax correctly." I started laughing at him  and this made him even madder. I said "You listen to me and you listen good Scum bag!! You all are nothing but putrid  stinking scammers who will never amount to anything, you are all dooshes."  i then said well you reached a number that  will not fall for your scam. Of course then as I expected he hung up.
They are India toolbags all of of them.
