I called back and some guy with a very heavy indian accent answered with just saying hello. I asked who the f they were and he said that I won a gift card for 100 dollars..lol yeah right..and I will sell him a bridge in Brooklyn! Hung up on him. Could barely understand him anyway.
Same thing -- found it this evening as a missed call when I got home from work, no message. Given all the other shenanigans reported here I'm gonna block it.
