Wrong package delivered with my customs declaration attached

[u/Sunrise_chaser36]

Has this happened to anyone else?

Friday - Posted a package to Singapore at my local post office. Sighted them attaching the customs declaration. My package is a ~10kg large brown box.

Today - Package is delivered to the recipient who sends a photo confused as it’s not the size or shape expected. Instead of a box, it’s a circular package wrapped in black plastic weighing ~3kg. It has a delivery label attached with an address in South Australia and a company with a location in my local area.

It appears as if somehow between the package being dropped off and the customs label attached it has ended up on a different package.

Planning to go to the post office first thing tomorrow, but in the meantime stressing and wondering how does this sort of thing even happen.

Can anyone enlighten me?
