I gave a guy bad feed back once on ebay, about £3 fridge magnet.
It was a old plastic keyring with a magnet stuck on the back with a image printed out where his printer was running out of ink which had stripes in it and faded. (pretty much what I put on ebay)
I accidently left my mum and dads phone number on the ebay account when I moved and he was ringing them up shouting at them, then when they explained, I don't live here any more he was saying to come to my house and give me a seeing too. lol
ebay is full of weirdo's.
I changed the feed back to positive because I couldnt be bothered dealing with the hassle over £3.
