After sales call with no consent given

I can't start to explain how frustrating it is to block call after call from Hippo.co.za I already did the check for quotations and did not consent to being contacted afterwards. Then the guy I spoke to explained they had to complete the quotes, thus the reason for the call. When I said I didn't see anything I liked and that I did not consent to receive a call, he hung up on me. Guys, if you need a quote for insurance, rather call the insurance companies directly as clearly Hippo.co.za is above the POPI Act....
