I had a call from this individual today (Martin?  Indian accent I think) claiming to represent a mortgage broker.  He called first time with an unavailable number and I told him to get lost then he called back and was extremely forceful and the caller ID showed this telephone number.

This one is bizarre...I'm in Calgary having just returned from New Orleans, and my wife is there for another couple of days. She calls me from New Orleans and the number that displayed on my cell was (403) 508-9892. I tried dialing that number but it isn't in use. Unless both called me at precisely the same moment and when I answered, it was my wife who had made the connection. Weird!
