Apparently I am a valued customer at some unmentioned store, and am eligible to receive a $100 gift card that's redeemable at stores I don't shop at. In other words, it's a scam. I didn't press 1.
Like the others here, I don't answer un-ID'd calls. Caller did not leave a msg, now added to call reject list. Thx for the comments to weed out these cons. :-)
