I bought a bundle of nice M&S baby clothes for 99p + £4 P&P. It was marked as despatched 2 weeks ago but hasn't arrived. I messaged the seller who replied after I opened an 'item not received' case. She said that she'd sent and has a receipt to prove it, and that the other item she sent on the same day arrived with the buyer. Then asks 'so where do we go from here?'
What should I do now? I've paid for something I haven't received so I'd like my money back, including postage. Would it be unreasonable of me to ask for that? Should I just accept that I've lost money? I feel like it'd be a bit petty of me to ask for £5 but I've lost that money and a set of cute clothes I wanted.
