Marketing Calls Wont Stop

Homechoice keeps calling me trying to get me to buy on credit. And although i appreciate the call, my frustration is that i have indicated to many of their agents/consultants that i do not wish to receive such calls anymore. I keep blocking the number they call me from and they keep getting a different person call me on a different line.

I am begging. Please. I do not want to receive calls and would like for Homchoice to stop calling me.
