Liberty Life Harass calling

I have never in my life met such rudeness. I tried to politely decline the insurance being offered, as I didn't want the sales person to suffer from my irritation of being cold called when I have never asked for any services from Liberty. However, despite declining several times (initially politely) I ended up having to simply disconnect. The sales person then proceeded to call repetitively up to 5 times!!! I mean what the heck? Is this how Liberty conducts their business? Harassment? I will now NEVER buy anything from Liberty!!!!
