this is not american express... i keep getting calls from this number and 623-492-6031 from Phoenix, AZ.

They have the wrong name and phone number they claim they are dialing.

I called american express from the number on the back of my card, and the cust. service agent told me to file a report with the police for these numbers.. i dont think the police can help, but these people sound very much like Amex, they even have the recording beep in the background, just like Amex.

Be careful not to share any info with this fraudulent company claiming to be AmEx
Caller ID: 210-232-3974
Caller: claiming to be American Express, false
