Globe Life & Accident Insurance Co No medical history needed, you won't be denied. Oklahoma City, Oklahoma

I was applying for life insurance, sent in my $1.00 to start my policy.  They state right on their paperwork that no medical conditions will be refused.  I was later called and had to tell them that I was under a doctors care for multiple medical conditions, which apparently each person on the phone can, in my opinion, decide on a whim whether they want to cover or not.  They had sent me a letter back declining me cover and also a check for my initial $1.00 to start coverage.  Now i am getting multiple mailings from them all the time.  I want them to stop contacting me for good.  I wanted to get a life insurance policy last year before I had my knee replaced, but they couldn't see that my health was that good to do the underwriting.  To me, sending me all of these mailings every week, sometimes even 2-3 times in the same week trying to get me to sign up for insurance for myself (which I already know that they will not cover) or insurance for my son, is getting ridiculous.  I thought that when I did talk to their customer service people the staff was somewhat rude and didn't really care about who the person on the phone was that they were talking to, or in my case a (would be prospect?).  I have many friends, and they can tel many more friends about what this company has done to me.   Anything you can do to help me get these people from sending me mail would be greatly appreciated.
