Who called from 3345216646

I've received a call from this number a few times recently. They never leave a message.

Call, never answer, never leave message.  Just plain annoying.

I keep getting calls from here; called twice yesterday and it displays as missed calls.  Very irritating!

They keep calling, letting it ring twice, and hanging up...no voice mail. When I finally decided to callback, they said I visited an affiliate website of theirs and won a $100 gift card. Sounded scammy.

This number has called me 3 times and does not leave a message.  I research number and it is a telemarketing scam-something called "Gift Services".  Give your info and they give you a $100 giftcard that apparently never comes.
