Got a call from 11-905-993-1212.  The "11" at the beginning threw me off and I figured it was a telemarketer so I didn't answer.  No voicemail left so it can't be anything important.

this number has called me twice now.  in a span of 5mins.  
no message.

I received a call from this number but my cell was off.  No message left.  I am happy I did not answer because it would take up my minutes!  Stupid unknown critters!

Got call from this number twice today, didn't answer and hate to receive unknown calls.

I just got a call from this number today.  I didn't answer and they didn't leave a message.  Probably was "selected for more free airmiles"  :P

"You have been selected for free air miles" or something to that effect. I have never used air miles. I also have never gotten one of these spam calls before. Very strange.
