i got a call from this number twice a week if some body knows it

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.

Says they are "Bell Mobility", usually calls multiple times daily and do not leave a message.

I am getting calls from  (780) 424-5841 the display reads unknown--when i answer they hang up--i call them back and a message says that the number is not asigned.

This number, (780) 424-5841, has called me 3 times today. When I finally answered it was BBC or something marketing, looking to do some kind of survey. They knew they were calling a cell phone, asked them how they obtained the number, was told it was on the computer, asked her how the computer gets the number. Said she didn't know but could ask her supervisor. Asked her to please remove my number from her list and she said "Since you said list, we can remove it from the list"Wtf....

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