I called the toll free number from a secure line to see what this is all about. They are basically trying to get you to do a 7 day "no commitment" trial for an identity theft program. You have to pay $9.00 for them to ship the $100 gift vouchers to you. I did not go any further than that.
Got same message as "SUE" but mine said I won $100 Walmart card and to call 1-888-511-9314 to claim. To end msgs reply stop. I looked online and see that this is probably a scam from all your replies. I plan to erase the text and do nothing. Thanks to all who posted similar messages!
