Leave me alone

I have never had any dealings with any Discovery products in my life nor will I ever use any of your products yet I am bombarded, almost on a daily basis by tele-marketers wanting me to sign up for your products. I have asked repeatedly that I stop receiving calls from Discovery, yet they keep on coming. I am sick and tired of hearing the name Discovery. Where did you get my number from??????. Please stop calling me, irritating me and wasting my time. I AM NOT INTERESTED
