Who called from 2033430456

Automated call,  unknown company,  googled the number  it is a "gift card" scam  No answer on call back  What happened to the DO NOT CALL LIST

This number called my cell and when I answered they hung up.

Rang to my cell today but no message left. I never answer numbers I'm unfamiliar with but seriously doubt the DNC list will keep them from calling back.

REceived call from this number on my cell phone yesterday...  as usual these SCAMMERS did not leave a message.

no answer when  I ask who is this and why are you calling;  I told them to stop calling but they persist.
