I bought something from eBay on 23rd Nov but seller was out of town at the time. He came back about later and sent me a total invoice because I bought multiple items and wanted a combined P&P. I then paid on 29th Nov. The package was sent and then held at customs, I paid the fees etc and it was released for delivery. Christmas came and went and the package was still not arrived, so I call our post office only to find out they couldn't locate it. It's been declared lost. I want to file a non receipt but I understand in this case it's not buyer's fault. So I would like to give it as much as possible for the package to turn up and file as a last resort. So is the time limit for filing 45 days after purchase date or payment date? Thank you for your help!
