Constantly calling me without permission

Over the past 3 -4 weeks I have received atleast 10 calls from [URL Removed] regarding motor insurance as well as Medical Aid. I have never indicated that I am interested on their website and have only ever used it for making comparisons. <br> <br> I have also received calls from Geneis health who tell me that they received my details to quote on medical aid from Hippo. They are clearly selling peoples details and harassing people with numerous unwarranted calls. I will escalate this further if I am phoned again by Hippo without indicating that Im interested, if I ever trust their site again.
