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.

I just received 2 missed call from this number. Very wierd cos they know both my cell and home phone numbers. Can someone please track down this number and shut them down please....

I got called at 5:55pm Friday November 6th but I didn't answer it as I didn't recognize the number.  I've tried reverse look up but nothing comes up.  Luckily I've only been called the one time.

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.

Got a call 7:38 from this #. It's an Edmonton #, or seems like one. Same MO, not in service.

I continually get calls from (780) 424-5841.  If you have the capability to block numbers on your phone - works like a charm - problem solved!

I tried to call the number back, but get a recording stating the number is no longer in service - strange....
