USPS tracking?

[reconn2000]

Hi, im in Queensland, Australia and i purchased an item from a seller in the US but they sent the wrong part.

Upon telling the seller, they said they would send the correct part and supplied me with a USPS tracking number.

But the tracking is saying the item was 'Delivered' to an address in the USA, Kentucky.

I told the seller who replied with this answer.

Hello
your item is in transit to your destination. The Kentucky address shown is the USA departure point.

The tracking info was.
