If everything besides the communication is a positive experience I would leave a positive feedback. However, I would leave a one star rating on the communication. A one star rating is worse for a seller than receiving no stars at all. (You might want to look at her communication star rating, she may have others) If she falls below like 4.5 or something like that ebay could ban her from selling (not that I'm saying they should) All I mean is if you leave one star for communication maybe she'll realize she needs to improve on her communications.
