Hello, Lancer pointed me here, I'll add my two pence also. I am in exactly the same situation as others, this person bought 8 items from me in November totalling £32. I sent my items via Recorded Delivery (trying to find my receipt right now), and left me 8 positive feedback. Additionally they purchased from me before, but no problems.

I will be replying to the case with screenshots/scans when I've put it all together, as Lancer has. Thanks for sharing information here. I hope that there is a positive outcome to this! x

Edit - Found the tracking receipt, I looked it up online and shows a digital
Signature and printed name with the same surname as the buyer. So they can't claim they didn't receive the item or didn't know anything about it ALL this time. I'll screenshot this also. Is there an email address to send this stuff to? Sorry, I'm not 100% on the process.
