I just got the call too. Didn't recognize it so I didn't answer. No message left. Caribou, Michigan is the location of where the calls are coming from.
They called me at 10:15pm and woke my 19mos son up! I called back and screamed at the rep and told him it was illegal in CT to call after 9pm. I told him that I was going to report him and the company to the better business and that they will be in a world of [***]! I made the rep cry. He was actually sobbing on the phone begging me not to report them. It said Gifts 4 Free on the caller ID and they claim that I signed up for a Walmart gift card. They wanted my CC # to process $4 s/h fee! SCAM!!!!
