Harrasment by dropped calls every single day!

I have already reveiewed this company ina very negative light because of the never ending dropped calls. after receiving 2 separate emails from Talksure assuring me that I have been placed on their DNC, I am still receiving 2 dropped calls per day. I have written, called, emailed, complained and threaten legal action but to no avail, I even cancelled a policy associated with Talksure but still they call. Pls can you stop calling me!
