I bought an item 7 days ago. Seller has used Royal Mail tracked 48 and sent the attached photo as proof of postage. Royal Mail tracking is saying they're 'expecting the item'. Seller is insisting the item has been sent.
I've never used RM 48 hour tracked before so I don't know how it works but I'm wondering if the proof of postage attached is generated online when you pay for postage rather than when you send it. It was sent to me a fee minutes after I bought the item at 9pm so I cant imagine that's been done at a post office.
