WORST INSURER BY FAR

I went onto Iwyze web and asked for a quote for my home building as well as home content insurance. Like most sites (and this is making me furious) I had to enter my name, surname, id no, cell phone no and select what I want to ensure. I got 7 different people phoning me over a period of ten days who wants to "assist me with a quote". The very first question from all of them was, "WHAT DO I WANT TO ENSURE" So my first reaction is what is the purpose of asking information on the webb site, my second question is why or how did this person know to call me? Did my phone number just mysteriously appear on her screen! Then all of them start asking me the exact questions about myself although I did complete the online form with the relevant information. The crucial part is that after 7 calls I have not once complete their questions and yet to receive an quote, I even mailed my current insurance policy to one of the ladies so that she can have all my detail, can see what I have insured, for what amounts and then try I beat the price, I did not receive anything from het either. Now my biggest concern is, I do have a policy covering 3 home buildings with them, HOW MUCH EFFORT IS IT GOING TO BE TO CLAIM
