Non-stop calls

I am currently doing research for a pet insurance for my puppy, and was looking into Dotsure.co.za. I went onto their website, and I had to fill out my details to get to the different plan options. Once I found the different plans and their prices I had all the information I needed. Since I filled out my information on their website, Dotsure.co.za has been calling me non-stop. They have also sent me numerous emails. I was simply just doing research on their plans and prices, if I wanted to contact someone for more information, I would've done so. Dotsure does not need to phone me twice a day, every day. Please stop.
