Who called from 4075301013

called once, hung up. wtf

got about a half a ring before it hung up. Having heard of scams that ring once and then hangs up. I wasn't about to call back.
Plus, any relatives I have know to leave a voice mail for me.

Called Rang once and hung up.  This was only an hour after registering a rewards card for a large grocery chain.  Coincidence???

Called number back and the recording says I recently visited one of their affiliated websites and have won a $100.00 rebate card for a popular retailer. Press 1 to redeem card, 2 to be removed from their caller list. 2, 2 , 2 , 2, 2, 2

Came up as John Doe on my caller ID. Block
