Got a recorded message telling me they regret to inform me that my mastercard has been disabled.  To reconnect, press 1.  Pressing 1 the recorded message says to enter your 16-digit card number. NOT!

Got the same call 3/2/11 4:36pm PST. My bank confirms it's not them, actually lol.

Got the same call just now, was about to enter my info and then wised up and called the customer support on my bank, they said my account was fine. Scam for sure

Got the same call now advising me that my MC had been locked to press 1 to be connected to their security department.

Just got the call now and googled it and seems like more and more people are getting this call. Didn't pick it up though.
