I was having a problem with spam calls
Eliminated 99 percent of them, im down to one call center spoofing numbers
If it's a man, I start impersonating Apu
"Why hello my friend! It is so good to hear from you. And how may I help you on this wonderful morning? "
They don't like being talked to like that for some reason.
If it's a female, I ask how much she charges for head. They get belligerently mad when I ask that question, I have no idea why. It's just a question. But they never call again
