6could not find this number listed as an official American Express number, I think it to be bogus! Asked for my social security number and that's when i hung up.
Multiple calls from this number with voicemail indicating they were American Express trying to confirm a request and indicated a pin number to use. I have not made any requests with AMEX.. This is scam phising.
Did not answer. On Voice Mail they said they were from Wellcare. Checked with Wellcare and it is not one of their numbers
Amex application verification scam carried out by individuals impersonating American Express representatives.
