The lovely railway layout?
That was paid on the 3rd so you have waited long enough. It was a lot of money paid , so nothing one would assume you just forgot to collect! Let's hope nothing bad has happened here, but it may have !
Send a polite message, saying something like.... 'Hoping everything is OK but if you could please let me know within ** days of a convenient time and date to collect, but if not I will need to cancel the order which will fully refund you. '
If you do need to cancel the order select Buyer requests to cancel. This will fully refund your buyer , and your seller performance will not be affected.
