I've only given one negative, very recently.

I bought some jeans off ebay a month or three ago ... emailed to get her DD details, she gave them to me, I paid same day.

Item didn't arrive after a week ... two weeks ... three weeks ... either no response or "I've already sent it on X day". I opened an "item not recieved" ticket, she never replied. When I closed it from no action, she said it was because of the "floods". Which I looked up and found that the floods were real but happened about 2 weeks before I won the item, so she managed to list all these items for sale but couldn't post them? Riiiiight.

I left negative feedback when it hit 6 weeks since I paid. I wasn't the first - she had quite a few negatives, much the same.

She promptly opened an unpaid item case (despite saying she'd sent it several times - why would you do that if it wasn't paid for?) and I said I'd paid, on X day, to Y bank account, check your bank statements from 6 weeks ago dammit. She closed the unpaid item case with no strike against me.

Item arrived 3 days after the unpaid item case closed.

She could have just sent the damn thing the day my payment hit her account!
