definitely leave her a neg, you have so many reasons to do so.
Well, on one hand, yes; multiple things went wrong and I could neg her.
On the other hand, as I mentioned, she did finally agree to compromise with me and issue a partial refund, so I feel that a neg isn't really warranted at this point. To me, a neg is an absolute last resort when a seller just simply isn't willing to rectify a situation, KWIM?
