Ebay nube here - I posted an item two weeks ago (Royal Mail 2nd class, as per listing) and buyer has opened a case saying it's not arrived, and asking for a tracking number.
The thing is, how do I really know it hasn't got there?
It's doubly annoying because I underestimated the postage and ended up paying more than I'd listed.
On the practical side, should I ask her to wait another week to see if it's turned up? There have been a couple of bank holidays in that time.
