Received a call from (780) 638-6515 on 7/20/2010 @ 4:55pm. Caller ID said Alberta and I didn't recognize the number so I didn't answer. My phone recorded their recorded msg, very garbled, especially the parts where they say their company/bank name and what account of mine was supposedly compromised.  I was to press 1 to be transferred to their security department.  
This call reeks of a scam.  DON'T ANSWER OR CALL BACK.
The 780 area code is in Alberta Canada and I seriously doubt any U.S. company I do business with has a Canadian security branch that handles US accounts.

got a call from this number - same story as everyone else.  I couldn't understand the name of the bank on their recording, but they wanted me to press "1" to be transferred over to someone who would help me as one of my accounts had been improperly accessed.  I called the number back, and got no answer after ringing about 10 times.  When I called again, it was busy. PHISHING SCAM!

This number just called me and did not leave a voice mail. From the comments on this site, it seems it's better than people don't answer.

They want us to pull our car over and turn around ????? Asked a bunch of questions

Midnight 7/19, garbled and hard to understand, something about my bank account. Called back, busy, and then no answer.

Just got a call from this number, recorded voice told me that one of my accounts had been accessed by a third party.
