Really? I had no idea about that, I didn't see anything about that on the feedback policy page.Just for future reference, do not mention a case or anything like it in feedback. EBay may remove it if the seller complains.
Thank you for noting it, I'll be sure not to in the future (hopefully there will be no need for negatives though!). I find it odd, as it's not saying anything untrue. I hope it isn't removed personally, as that negative was wholly deserved and I'd like any other future buyers to be warned about her.
