He has seen the tracking details & signature of receipt at Royal mail website, but denies signing for it, the signature is digitized so is unreadable. He's opened a case with ebay but I spoke to them before he opened the case & they said if I give tracking details & it has been delivered/signed for then they will find in my favour. Just wondering who is the loser , ie do I refund or not ? I have in the past had signed for items just posted through my door, no signature, just wondering if the postie couldn't get an answer, signed it himself & just posted it, then the buyer decides to try it on ? I understand posties are at full stretch at the moment so are trying to save time.
