I started answering scam calls. And pressing 1 when it said so to speak with someone about my microsoft account, apple account, car warranty, etc. And telling the person on the other end to kindly fuck off. After a few rounds of this, the calls stopped calling, as I'd gotten on enough of the spammer blacklists of someone who will waste their time. It took a while to build up the courage to do so, but I'm glad I did, because when the phone rings now, I can be reasonably assured that it's someone who I actually want to talk to.
