Origin5 selling personal information

I have reason to believe this company is selling my personal information. I keep receiving calls from insurance companies, and when I ask where they got my details, they consistently mention Origin5. This is a serious violation of my privacy, as it is ********* to sell personal information without consent. What’s even more troubling is that I have never interacted with Origin5, so I have no idea how they obtained my details to pass on to other companies. I’ve blocked over 80 numbers, yet the calls persist, leaving me with no peace while using my phone due to this constant harassment.
