this number called and left a message. it was an automated voice, said lauren matthews form the canadian revenue agency was calling. id number 6135021148 which is the same as the phone number!!!!!!!! its toally a scam, besides if it was important im sure there would be a real human and not an automated one.

Same as Sarah and already had the same kind of message from1-613-699-3304, from a man that time.  Don't be impressed by their threatening tone.  Just ignore them.  If it is really something important a machine wouldn't call you.
