Thanks again, folks. Elphaba, thank you for reminding me that it's not my job to seek legal action. I removed all that from my letter.
So I wrote a two-paragraph e-mail back to her, went over every line with both ktspktsp and my dad (whose second job is as a salesperson, but an ethical one who knows his stuff), and called my friend in law school to get her opinion.
I'm still going to wait until morning to send it... just in case I decided to reduce it to a few lines instead. As in, "We have a misunderstanding. I did not sign a contract of any kind and therefore did not agree to pay you any kind of fee. I will not pay you $300."
Mostly, though, I wrote out a bit more because I knew that if it was short, she would respond with all kinds of defenses and assertions... and I wanted to cover those in my e-mail so she would go away and never come back. I hope I covered all the bases... we'll see. Will send in the morning and get back to y'all.
