Non stop Spam after using them to find insurance

I used the website to get a quote for insurance last year. I clearly selected that I did not want my information shared with 3rd parties nor did I want to be contacted. A year later I still suffer from spam calls or insurers soliciting me, during work, at church, important events these calls will occur no less than 3 times a day. It’s 2.30pm as I write this and I’ve already been called 4 times! For a service I was looking for LAST YEAR😭 There’s no break. This is harassment. Can I get my details removed? How are you complying with POPIA if I’m getting these calls but I clearly asked not to? Please do better. I wouldn’t recommend using them. Rather a broker because your information is safeguarded.
