This is a person that call to harass peoples for no reason

Spam number that send threat message, very scary

my father keep getting threatening calls from this number and he's 85 years old. your'e a miserable looser to do that to old people it's a shame

Get your father a call blocking device and block them.Most devices are running just a hair under 40 at the moment and you can google them.  Also file complaints with your phone service provider and local LE.
