what has happened since then? I also have been getting these threatening calls.....

My brother started getting these calls. The person who left the message was stating something about pending cases filed against him and a summons that was to be issued to him.

But, whoever is calling and leaving these messages is also leaving a call-back number of (888) 762-1254 (which, after searching on this site, happens to be another reported number). Calling back does no good since no one even answers. Very aggravating to get these calls daily!
