Can I take legal action against this Sales Network

I put my motorcycle up for sale on Craigslist. I started receiving calls from a company call Sales Network. They called twice, left a message, then I finally talked them. They told me what they had to offer, i asked them to email me information on their company and I would look into them and call back if I was interested in their services. After researching them I was no longer interested, continued to receive call daily. I finally picked up the phone when they called, told them I was not interested and to please take me off the call list. The operator "Cory" very aggressively kept asking "why why why why why? I said it did not matter why I am just not interested. Then he said he would not take me off the call list and hung up on me....
