I received a call on my cell phone at 5:14. The connection was not very good, but I did hear "your mastercard". The call disconnected after 30 seconds.
Called cell at 10AM saying my AMERICAN Express card has been blocked from usage and to reactivate it to press 1 to connect with the security dept. I do NOT have an AM EXP card. (Just like the ppl who said they got the "M/C call.") Also, when I looked up the #, it says the # goes to LORDLOVELIFE.COM. SCAMMER. I'm calling AMEX next to tell them.
