I think it may be because her feedback is so old that with the new system it doesn't show.Her feedback is so misleading. She's got 111 @100% and yet you are her very first customer! I recommend you file PayPal dispute and escalate it to claim immediately. Too bad you've already submitted feedback. I've no doubt PayPal will recover your money though it may take a while. Good Luck to you!
If check her feedback left for others it looks like she tried to sell an LV too.
