Stop Calling Me, Just STOP

I bought 1 item a year ago and for the life of me cannot get them to stop calling me. I keep telling them not to call but they hear the opposite. I don't want a discount or free mystery gift from homechoice. I dont know who I can call, tell, email, ***eon msg. Why do companies and people not listen when you request a simple thing gosh I'm annoyed. I will never buy from homechoice cos they an uninvited guest that won't leave.
