I received 2 calls from this number that I did not recognize.  I did not answer either of them.  A few minutes later I received another local call which I answered, but it was somebody complaining that I had just called them.  I believe that whatever service which called me using the 780-669-9312 number made another call using my phone as it's ID.  Which means that perhaps when you try to call it, 780-669-9312 is rerouting to the last number it dialed somehow, or perhaps it just belongs to some poor sap who got his/her number ID borrowed like I did...
