I sumbitted a request for a Quote on insurance, the day after I submitted the request, I started getting calls, about 10 a day mostly from them trying to sell me insuance, I told them I wasn't going to buy from they, especially after they repeatily called me, I ask them not to contact me again, but I am still being contacted by them, I have filled a complient with FCC and bbb.org, and they are still calling, I have ask them 3 times to stop calling me, I also started recieving calls from other insurance compines after I submitted my request. I can't understand what makes them think that they will get the sale if the call someone over and over, on one day they call every hour on the dot.
