Just as a follow up to my post above - I tried calling the 424-230-4672 number. No one answered and a recording said the voice mail box was full. Even more reason to believe this is a total scam.
My wife received a text message from this number which said, "Special thank you for our registered users. Please call 8556699796 to claim your $100.00 Wal-Mart Gift Voucher!" We have no idea who this came from. My advice to anyone else who may receive similar texts is not to respond to it as it is no doubt a scam of some sort.
