Has anyone dealt with Berman Rabin debt collection harassment?

I’ve been getting constant calls and letters from a company called Berman Rabin about an old debt, and it’s really starting to mess with my peace of mind. They’ve been calling multiple times a day and even reaching out to my family, which feels completely over the line. I started looking into it and found this page that talks about how to stop Berman Rabin debt collection harassment and what your rights are when dealing with aggressive collectors: protectionforconsumers.com/stop-berman-r...on-harassment-today/ .Has anyone here gone through something similar or taken legal steps to stop these calls? I’m curious if others have found success with sending cease and desist letters or working with a consumer protection attorney. I’m honestly just tired of feeling anxious every time my phone rings. Would really appreciate any advice or personal stories about dealing with Berman Rabin or other debt collectors who don’t seem to respect the rules.
