I sold something on eBay, by recorded delivery. The person sent me a message saying he hadn't received it. I tracked it and it's been received and signed for (by a different name than he's using). I sent him a message saying from my end it's been signed for so it must be there somewhere. He sent me a message back saying no I haven't received it. Argh. Where do I stand. It cost me £7 more to send than I made on it!
