The guy first gave it to Hermes in Germany. It was the only one available through the post office - without the need to get someone to come at your home or workplace and wait for them.
Then Hermes gave it to post.at, which is Austrian post office. I bet the f... up was on my side, Croatian side. Austrian post office gave it to a transport partner in Croatia and they are the one who said they attempted 3-4 times - I can vouch they didn't.
What I mind the most is they not calling me. They had the number. I would explain where and what... Another thing is, the tracking number was of no use. Going through tracking services, I couldn't detect which delivery was it. Otherwise, I would give them a call, gladly to help them find me.
I'd say, here

It's the first result under the ads!
They spoiled my Christmas. I should be allowed to sue!
Oh, I'm just farting out loud...
