How can I reliably screen or block callers on a number-by-number basis?
I've been getting calls from a strange number recently, and it's not even a local area call. This caller has called me 20 times, and whenever I pick up the phone I am met with intimidating silence, even if I shout in it.
Naturally, I decided that I had enough, and tried to surf the internet finding ways to block certain phone number. However, the only methods I found were to either:
(1) Call your call service company to block a call,
(2) Install some apps to do it,
Now, I do not want to overcomplicate this situation, and I've had bad experiences with applications... so, any suggestions on how to deal with this?
