I keep getting calls at all hours from this number asking for different people.

I just got a call from this #.  The fellow on the other end was telling me my # was selected for a cell phone promotion fro Bell Canada.  Seemed rather fishy, when I told him I already had a phone and didn't need another one...insisted it was absolutely free.  Kept insisting it was free, no strings... I said NO and he continued his spiel.  It was his insistence and the mention of "just taking my contact info" that seemed odd.  I declined the offer and said goodbye.  Tried to reverse look up the # and nothing showed up.

I supposedly got a voice mail message from "Chris from the Edmonton Oilers" asking me to call a 1-866 number - I did not return the phone call.

I got call from this number and asked my credit card no. to activate automated online profit system account. Do someone have received similar  call?

This number is a spoof.  The call is probably coming from a VOIP line somewhere outside Canada that is being used for scams.  Just fart into the phone and hang up.

That number is a identity protector number for example. Some home phones dont allow "unknown name unknown number" or "private name private number" So the phoe service provider give them a "fake" number to call you with. Some even have fake names.
