How do I know when my rewards expire. On my statement it tells when soem of the rewards expire which total about 14.00 but I have over 100.00 more that I am not sure how long I have before they expire. I called the 1-800 number for my card but the guy said he couldn't tell me when they expired, just 3 or 5 years when I got them, don't remember which he said. Did he not know what he was talking about or is this just a guessing game of when they expire????
