Pushy Dirt bag is back

This jack [***] called successive times in a row even after I did not answer the first few. Calling from a "private" number, so after the forth call I answered thinking it could be important. Ha, I told him I was forwarding his call to police and started dialing. He then called back 2 more times and both were unanswered. He is making it impossible to block as he is using a "private" number. So I just reset phone to block ALL :private" calls. More than one way to stop idiots.
