Just got a call from them.  They hung up so I called back and got a recording.  Pressed 1 which connected me with an operator.  As soon as they get you on the line, they say "Hello what's your first and last name?"  I decided to have some fun with them and called back several times asking them what their first and last name was and telling them that I was from the redemption center to offer them a $100 reward card.  They propmtly hung up.  I guess they don't like getting calls from telemarketers or phone scammers.
