I received a call from this number and the caller was listed as V02510013200042... What's up with this seemingly new tactic???

Yes, another call from this # and no one on the other line. Will have to block call in order to stop the calls.

This number has been calling me about 10 times a day for the last week. Does anyone know how too make it stop.
