I've never sold on ebay before, and have just gone to leave feedback for my buyer, but can only leave positive. They were late paying, didn't contact me at all even though i'd asked her to when she received the tickets to let me know they'd arrived etc, and hasn't left me any feedback at all even though I did everything I said I would, at the times I stated, and kept her updated all the time with tracking numbers etc.
What do I do? leave pos feedback, but explain that actually she was shit?
