Textg Msg from American Express stating "AMEX will never call you for this code: ________ (I don't want to repeat the number)...for onlline use only. Call 8005284800 now if you did not request or if you released it to someone who called you." I looked on line for AMEX customer service and this number came up. I called and was told at 8:00 AM EST that the Fraud dept comes in at 9 and someone will call me. If I don't hear in 24 hrs to call back. Again I looked the number online, now it says Fraud today. How can that be. It wasn't there yesterday, I looked for any fraud notations. What does this text mean?
