Term Paper Relief Plagarized My Entire Paper

I purchased a 3 page paper from Term Paper Relief and they had two weeks to do it. Not only did I recieve my paper 3 days late, but I also recieved a completely plagarized paper except for a few sentences. The paragraphs were taken word for word from two websites that I found. I called them several times to complain and all they kept saying was that they would revise the paper for me. I gave them all of the info to revise it, even though I just wanted my money back. I gave them my new due date which was 5 days later and again never received my revised paper, so I called them and they said that they never recieved my revised form from their website. At this point I was furious and told them that I wanted my money back and they actually refused and kept disputing the plagarism, even though I sent them the paper back, highlighted the plagarized paragraphs and gave them the exact sites from where the plagarism came from. I am so pissed off and want to find out a way to get them out of business, hurt them financially in some way. Does anybody have ideas on how to accomplish this? Samantha
