Do you have proof of postage from the Post Office?
It is a bit silly, but it does mean that buyers can leave negative feedback, if warranted, without the worry of getting negative back. It happened me before, I left negative feedback for a bad seller and got a negative back, even though I paid instantly in full which is all I can do.
Really should have sent recorded, especially around Xmas where packages go missing all the time.
Sorry to say you are stuffed. Only a recorded postage option will stand up if he makes a claim against you - unless he has a history of doing this in which case you have a slim chance.
It's not fair but some people just wait for this sort of thing so they can take advantage. Alternatively he may be telling the truth although I have to say I post loads and it's over the years only 2 things have gone missing.
Nope, I got someone to post it for me because I was too busy with work. Thought this might be the case, first time it's happened in 9 years so ah well! Thanks all
Stinker mate, its a shame its happened but look at it the other way Its only £27 and not a few hundred. Lesson learned the hard way I'm afraid, at least you won't do it again.
