My Dynasty Sales Ripped me off! Internet

A young women came to my door and said she is a student at the University of Houston and she is a theatre major. Her class is doing a fund raiser to raise funds for the class to study abroad in Europe. To raise money she was selling books. She showed me her student ID and everything. I invited her into my home, looked at her products, and bought some. I spend over $100. She was very polite and convencing. She said the books would arrive within 3 weeks. I never received them so I started researching the company and found many reports of fraud.
