Homeschool Stockroom scam, false advertising Rochester, New York

I ordered homeschool materials from Homeschool Stockroom on Feb 21. I received some materials that were nothing close to what I had ordered, more than 2 months later. The website specifically states that my $400 order came with text books and a variety of other items that were not included in the order. I called to let them know I was sending the order back, and the woman (the only person who works at this "company" I might add), said she would let me speak to a supervisor after arguing with me about the fact that her site specifically states there won't be substitutions to your order(that you will receive the exact materials ordered),  and then hung up on me. She preceded to pick up the phone and hang up any time I called after that. Finally, my boyfriend called form another number and she answered. After threats that we would sue her, she gave us a "RMA number" to send the merchandise back for a refund, which we did immediately, and with a signature confirmation number. She is now refusing to accept the merchandise, as a notice has been placed on her door by the postal service, and she has yet to receive the package. This woman is the biggest SCAM ARTIST I have ever encountered, and she needs to be stopped.
