I too, have had the same calls for the 3 weeks, comes up a +1 866-270-3021,and or
something very similar.
approx over 35 calls in the last week.

I think this is a "dummie" number. When someone calls from a calling card, calls off of the computer, or uses a scrambler..a phone number will come up on your caller ID. This number is not really in service, its just a "dummie" or masking number. I have had a few of these call me, and one was a friend who told me about this.

This number calls me daily, when I answer, I get loud beeps in my ear.  But I get a lot of phone calls from strange #'s that do that.Another Famous # is (780) 443-1480 with the name "Digtl contct" But the # alway changes.  I get these calls all hours of the night, and day.  I feel harassed.

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.

Weird. This number tried calling me on my cell last night at 8:51pm. I didn't noticed anyone calling me until midnight so I didn't bother calling back, until this afternoon. When I tried calling back, it said the number was out of service.

Just last week I got another weird call on my cell while I was at work. That number is a spammy number ( did the search on here) and that number is 780- 702-0874). When I tried calling back that one, it said that this number could not dial out because it is an answering machine(?!) Weird. But anyway, both the spam numbers area codes are from Edmonton and surrounding area ( including some of St. Albert, Sherwood Park & Stratcona).
