FCC bars providers for non-compliance with robocall protections

Before I got my phone number, a woman by the name of "Sade" has the number. Recently I've been getting at least one call per day from the same company regarding an extended auto warranty.

I've told them politely that this is the wrong number, they keep calling. I've asked them to take my number off their list and they happily agree to, but they keep calling. I've threatened to contact the FCC is they keep calling yet....they keep calling. I've tried to block their number multiple times, but they just keep fucking calling from different numbers.

I honestly don't get the logic of these places. "Hey this guy has told us 20 times in all manner of ways to stop calling him....but I think he might buy an extended warranty on the 21st call!!"

Can someone explain to me what the logic of these places is? It just seems like an absolute brain-dead strategy.

I never answer any calls from non-contacts because I assume answering automatically flags the number as "a live one" meaning "potential target who picks up their phone" in any number of nefarious databases. If an outside/unknown number needs me they can leave a message and I'll call them back if the message reveals them to be legit.
