Annoying calls

A week ago, I had requested a quote from the hippo website, I received call from different insurers as expected including Budget, my problem is that Budget insurance is calling everyday up to 5 times a day which is really annoying. I had rejected their quote because they were expensive, they don't give up. I had requested to be removed from their marketing list, since then I have received 10 calls from their agents. Stop calling me, it makes you look desperate!!!
