Anyone have any good ways of combating this? My spam calls have gotten out of control. I have Hiya, but it's useless 99% of the time since the number hasn't been registered to it. Every spam call I do the same thing. I block every spam call I get, but it's also useless, since it's an all new number every time. On my half hour lunch break today, just now, I received 4 spam calls, and blocked the 4 numbers of course. On average, I block 10 numbers a day. It's ridiculous. This is every single day. Is there anyway to only receive calls from people in my contacts list?
