I actually went through it all once last year (oh yes I have a house, sure it’s in central paris, of course I want a solar panel vendor contacting me…) and got the dude calling me, I told him about the spam calling and he was like completely taken back, he didn’t know what to say, I sincerely think he didn’t know him paying some publicity thing would end up like that.

Tried again but seems I’m blacklisted, not from the calls but from being called back 😅

Sorry for the rant, but enforcing it can be done like that I guess, but by the police ofc.
