I don't know why they are calling from a cell phone I think it's a scam because I don't even have an american express card account and they keep calling my house too
I agree that it is likely a scam, they were asking my wife all kinds of stuff that they should only ask the cardholder. Thankfully she did not respond. Besides, I do not owe them anything right now.
I just got the same phone call this morning, the number is American Express collection department. I confirmed it with Amex, but I still will not answer any questions from that number. Call Amex directly and ask to speak to that particular department to make sure. As a way to protect yourselves from Identity Thiet we all should make it a point to call the number on the credit cards and speak with them. Do many desperate people now in this recession. Good luck to everyone and be safe.
