I HATE SPAM CALLERS.
Download the app Robo Killer.
I used the apps trucaller, and hiya in the past. They are good too.
But Robokiller has an awesome feature that uses bots to answer the spam caller and annoy the spam caller!
Theres a week free trial and after that its $3.99 a month which I’m more than happy to pay!
(not a paid endorsement, i just really HATE spam callers and want people to defend themselves and fight back!)
