Had received numerous calls to my cell with no message left.  I finally answered today and it is Chase Bank calling regarding an old checking account that apparently had a small negative balance.  They confirmed enough info to convince me it's a legitimate number and not a scammer.

Its Chase, and i do owe them a small balance. Not fraud.

Guys, I think this is a legit caller. This number called my new work phone earlier this morning, I patched the call through to Jolly Roger, and the caller was a totally patient, pleasant call center lady who listened to the robot's ridiculous responses, and politely told the robot that she would call back another time.
