Being Harassed with phone calls for no reason

I was trying to read about the policies online and the website said I should enter my details to get a policy quote which I did, I understand that obviously they would take my information and call but I did not expect to be harassed like this. Yesterday I was called 4 times from *** and then today I was called 10 times by the same number which I have blocked because this is ridiculous. Now I noticed that I am being called by *** which I have just blocked as well. I was going to enquire about life insurance but the way I am being called so many times it has changed my mind, I dont want any product that belongs to 1 life, please delete my information from your database.
