What I'm saying is people on here are saying "proof of postage" is good enough.
As you've stated above, it's not - one needs "proof of delivery" - a signature.
You can all mock and correct me but it's the minority of items on eBay which are listed with the delivery requiring a signature. Most are first class and that's it.
Lesson learnt. I guess i'm lucky it's not more than £15.
EDIT - Wait a second....if he didn't receive it, he wouldn't have signed for it...? Your point still stands about being able to scam the Royal Mail.
With the above in mind, getting a proof of postage is ****** pointless.
