Ive had a similar experience back in December. Designed and commissioned some etches from PPD LTD, later received a small ceramic plate from a small company in the same town as PPD! Their package had been damaged, opened, repacked, and somehow the item for someone in a neighboring state ended up on my doorstep. Delivered by FedEx using a courier service, at which point neither wanted anything to do with the redelivery of the mistake. The courier's customer service number linked to FedEx, who told me to contact the courier! Back and forth and I gave up on dealing with FedEx as they clearly wanted nothing to do with fixing the issue. I ended up repacking it and reshipping at my own expense to the true recipient with USPS after contacting them.
Then my etches showed up later that week in a relatively undamaged package!
Not entirely sure how it happened, but dont fret, your loco may still be on its way.
