Who called from 8033366940

Called my cell phone Sep 02 2014.  Caller ID:  Edgefield, SC. One ring and then they hung up.

Same thing happened to me 9/25/2014.
called me.  i did not answer.  no message left.  Showed up from Edgefield, SC.

If you call the number back, you get a phony msg that you just won a $100 gift card "redeemable at popular locations"

I received many calls from this number.  After threatening to pull their fingernails out if they called again they stopped calling

Received call from 803-336-6940 on cell phone but did not answer.   No message was left so figured whoever was calling did not want to talk to me.
