I just got the same call. They left a voicemail stating an account was locked. Please press 1 to unlock! This is a scam, so be on the lookout for this call. Do not pass on any personal information!!!
I received the same call, but from a different number and for a different bank. (I saw this board when searching for terms in the message -- their phone number was private):
"Hello. This is an official notification from Eastern Bank informing you that your MasterCard has been locked for security reasons. To unlock it, please press 1 now."
This is clearly a scam -- it's the same message as above, but now for "Eastern Bank," which is a real bank in Boston where I live, but not my bank.
