Top spammer and non-adherence to POPI Act

I have never signed up to receive emails and I unsubscribe every time I receive an email, yet the emails NEVER stop! Hippo.co.za is harassing me and it infringes on my rights to protect my personal information. Where did they get my email address(es)? This company should be reported and sued for harassment and not adhering to the POPI Act. This company is *******!
