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
