Anyone else dealing with constant calls from Spire Recovery Solutions?

I’m at my wit's end with these guys. I started getting multiple calls a day from them, even after I asked them to stop contacting me at work. They talk about having veteran leadership and following all these rules, but their behavior feels like straight-up harassment.

I looked them up and found this article that breaks down exactly what they're doing and what my rights are under the FDCPA: https://protectionforconsumers.com/stop-spire-recovery-solutions-debt-collection-harassment/

Apparently, because they market themselves as an ethical, tech-forward company, their violations can actually work against them legally. I'm documenting everything now. Has anyone here had any luck getting them to stop? What did you do?
