Gotten three calls not sure what it is

Got a call from this number on my cell, which most ppl do not have the number for, on Sat Aug 4, 2012 at 10:16am.  I immediately called back on my landline... no answer.Edmonton, AB

Called, no message, and when called back it comes up as out of service. Most likely a robot call for Google as I have had several calls from Google re-sellers from all over US

recieved call from these guys on two diff cell phones and a landline...........did not answer and no messae as well just thot i wud google the number as very few have my personal cell and look what i find a**holes behind the counter lol have a nice day guys

Got a call at 1:30pm.  No voice, just a beep.  I hung up.

Called but missed the call and no message. Checked here as number was unknown to me.What concerns me more is that they have in some cases phoned both the persons home and cell within a short while. If it was an auto dialer working off sequential numbers that would not usually happen so that means a website has probably sold your info. We all seem to be getting this hit fairly recently so I now wonder if we share a common web site sign in history. ie the most recent sign in that I recall that was new to me was a real estate company login to get more info on a house. Anybody else have a recent history like that?
