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.

I have been getting multiple calls from this number, they claim to be a company called Express Transaction Services. The say I owe them money and I need to pay now or be sent to collections. When I ask them what the charges are for they reply, I should know! They then give me the option to pay half just to close the account, or I will go to collections. I told them I will wait for the collection letter, but they just continue to call and say the same thing.

says this number is not in service, called my work phone number, a message from a Jeff Ewanchuk

i got call from this number. i called back, said no this number.

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've been getting calls from this number on Nov. 27,2010 & called four times at my work number after hours.  Again on Nov. 30, 2010 two times again after hours at my work number.  No message is ever left.  Called the number and a recording came on saying the number you have dialed is not in service.  So i'm guessing this is a scam.
