NORTH SHORE AGENCY - NSA trying to collect for an appointment book i didn't order. then wanted me to pay for shipping to send it back melville, New York

i ordered a appointment book with my macys credit card from a company that sent me a n order form with my monthly macy's bill. the next year they sent me another one along with a bill for teice what i payed for the first one even though i didnt order it. i called the company  and told them to send me a return label so i could send it back to them , they told me i had to ship it back to them at my own cost which i didn't and won't. Now i'm getting collection notices from NSA telling me i know rught from wrong and the right thing to do is send them a check for 30 something dollars or they'll take further action. WTF i didn't place an order for the d**n thing.
