To be a dumb idiot is redundant and these callers are too stupid to understand the humor in being a double retard. They are probably members of the Dalits or 'untouchables' caste. I get plenty of scam calls and blocked everyone the first time; I never hear the ring anytime after that. I only see they called on my phone's screen later the next day. Get yourself a Panasonic phone system that blocks 250 numbers. A system with 3 handsets is about $100. Check Amazon.com for one. A nice feature is when the fûçk heads call back, there is no ring to irritate you. We are a sick society if we keep on accepting these insulting calls.
