This person with a heavily accented [Nigerian-like?] angry voice left a very offensive message on our department's business phone telling us:"Don't disregard this message---regard the call. If i don't hear from your attorney the only thing i can do for you is wish you good luck. As this situation unfolds . Goodbye and all the best for the legal case." Judging from the other posts on this page, I'm sure this is some sort of scam but it seems that when people call back, the person on the end of the phone gets flustered and hangs up. so if they're scamming, they're pretty piss poor at it.
