They called today and left no message

I received a phone call from this (780) 702-7489 and there is nobody there.  Is this a scammer number?  I also receive lots of unavailable numbers with nobody responding, I wait and then theyfinally hang up.

Have recieved several calls from this number. Does not leave any messages and when you answer they hang up?!

im geting repeted cals from this number dont know who is that

June 1, 2010780-702-7489 trying out the credit card points scam.  Some Mumbia-sounding dooosh.

Got a call to inform me that I had deserved a trip for paying my credit card on time. Began to ask me info on my credit call, which I didn't give. Very bad quality of reception. Appeared very suspicious.
