How do you actually stop Professional Adjustment Corp from calling nonstop?

I’ve been getting calls from Professional Adjustment Corp for weeks now, and it is honestly driving me crazy. They call multiple times a day, and even though I’ve asked them to stop, the calls just keep coming. It feels like harassment at this point.

I found this guide that explains ways to handle Professional Adjustment Corp phone harassment: https://protectionforconsumers.com/stop-professional-adjustment-corp-phone-harassment/

Has anyone actually used these tips or had success getting them to back off? I would love to hear real experiences because it feels like nothing is working so far.
