Who called from 5103767852

This is a credit card scam using American Express data. American Express' data may have been hacked.

Just got the call 3 hours ago, left a voicemail but it is unable to be heard?

I received a call from this # at 8:12 am. No message was left & I did not call them back. I do not know anyone in Fremont, CA & if it was a friend or relative calling me from there, they definitely would have left a message. Was probably a scam or telemarketer call.

I just got a call from this number, I have been on the national no call list since 2013, how did they get my number?  It was a missed call.

keep getting calls from this number, wanting credit card info....stop calling...
