I tried to file a complaint with Paypal, but it was past the 45 day period (a concept I didn't know about since this was my first time commissioning something). I don't know if that's what you're referring to or not.
As far as things I have tried, I have contacted her at two of her different e-mail addresses (with limited success, having heard back from her a few times but not at all in the last few months... she had at one point even said the vest I had commissioned was essentially done and would be shipped to me in a few days), and I have sent her multiple PMs on this site (which, according to her profile, she still frequents). I even tried contacting her on Facebook to no avail.
It's just incredibly disappointing to have this sort of experience be the one to set the tone for me of the whole idea of commissioning in general.
