Ostatni raz piszę i zobaczę jaki boot odpisze.

I still have the patience to reply but belive me that's not the only thing I do. Belive me, this is really stressful and I'm really losing my nerves.
I really don't get it. Can't you see that the parcel has been delivered to Australia to the correct address?

The truth is that there's no package registration on the Australian Postal Service if your'e looking for one there.

I can tell you from my experiance that Australian Postal Service does not register packages from Poland.

The buyersare aware of that, that's why they sometimes take an advantage of it.

If you've had some good will you could check it on international sites.
You claim that you've checked it. That's strange, I can see that the package has been delivered and you can't.
That's why I'm sendiu another tracking site link where you can clearly see that it has arrived and has been collected. Maybe here you'll be able to see it:

If this time the case won't be closed, I kindly ask for an email address to your superior where I can send a screenshot which shows the delivery information.

Three different people are replying my emails. This is irritating and unprofessinal

The buyer is taking an advantage to earn extra 219 EUR.
