I fucking hate phone scammers they call me every fucking day I tell them to kill themselves.
Telling them to kill themselves is the best method because they get upset and stop calling. Pressing 2 won't opt you out. Asking nicely won't do it either. You gotta get under their skin and piss them off.
The trick is to not engage in conversation, every time they retort just tell them to kill themselves. If they are black, kill yourself nigger. If they are woman, kill yourself fat ugly bitch.
I made some fat bitch so mad she went on for 10 minutes calling me a nazi. My retort? Kill yourself.
