Tried *57 that traces the call. Then call local law enforcement and they can get the info. Of course, the backwards police we have around our town say they can't do that. Perhaps your local police are more competent and can do it. Worth a try!
We received 13 calls from 863-438-7206 and getting the same problem with no answer or line not in service when we return call. Now we are getting one from 863-665-4948.
