This is a fake, bogus call from scammers. No matter anyone says on this site, it is a bogus number. One fool said, "it's okay. It's real, i work here". Give me a break. I get these 'american expres' calls from all over the u.S. I do not do any business with them whatsoever. If it was truly american express, they would leave a message. My bank does when they call and i am not home.
Claimed that they were calling regarding American Express Business Account. Gave 800 number to call back (800 952-6940). Asked to have account & SSN available when I call back. Called & told them I did not have an account with them, I was NOT interested in having an account with them & that my number was on the National DO NOT CALL list. They 'promised' that they would remove my number from their listing.
Got a call with that number where the caller's name should have been displayed, and the number 623-492-6031 under it. I let the answering machine pick up; instead of a message there was very heavy static with what sounded like an engine revving. That went on for about two minutes til I shut the machine off.
I was out of town for a few days. Got home and checked my messages and caller ID. Sure enough there was a number: 602-537-9012, with the number 623-492-6031 listed below. Didn't leave any message. Couldn't figure out who it was. Maybe I'll find out tomorrow if they call back.
