Spamming Without Consent

This company keeps calling me (different number each time) and it's really annoying. I have no idea how they got my contact information! The next time they call me, I'll submit a complaint under the Protection of Personal Information Act (POPI).

I need Prime Meridian Direct to stop calling me immediately and explain how they obtained my contact information. As well as when and how I consented to receiving calls from your company. I will reconsider my review once I receive this.
