How to defeat robo calls -scammers

I’ve been able to use Racism to my advantage when someone calls me from a random number I answer “Hola Como Estas” which is hello how are you doing. They think it’s a Latino the scammers suddenly lose interest and I’m like yeah they think I’m Latino they want nothing to do to me the language of money is English even to Indian scammers. I tried everything to get off lists for like home power solar or university of Arizona that someone angry at me signed up for speaking Spanish quickest way to get dropped.

So remember were all equal in America and not even scammers rob us differently.
