Per Caller ID, this came in at 1:56pm on 09/08/16, from Shook Hardy Bac (whatever that is; probably cut off). No message left, ergo not a legitimate business call.
Sorry; apparently it's Shook, Hardy & Bacon (or pretending to be) which is a law firm specializing in class action & product liability (as far as I can tell). Unclear whether they fight for the plaintiffs or defendants. In any case, they've no reason to be calling me.
