I did forget to add that I clearly stated in my listing that "I cannot be resoncible for any wrong infomation supplied by the buyer and/or if lost in post".
Though it's annoying that I threw out the reciept not realising it could have been important (and it was in this case). I guess I find it hard to take in that I REALLY did send the item.
Oh and I agree on the feedback front, eBay is a right farce now, it's a load of crap about sellers being dodgy, there's more dodgy buyers then sellers I am positive. If there are some nasty sellers out there the negative feedbacks will soon accumilate thus being banned. Also it's down to the buyer to choose a trusted seller. Even if it was the sellers at fault it doesn't justify removing the possibility to send negative to buyers to warn other sellers about them. This will be a ream come true for net ASBO's.
