And after looking up the ID's from the Technobit site, the Speedy site gave me DPD numbers as well. And hey, those numbers work on the DPD site
So it seems Technobit hands them over to Speedy, and Speedy hands them over to DPD (or something like that).
Downside is that both sites still state the package hasn't left Bulgaria yet
Anyway, I thought this information might be useful for some people here.
Thanks for sharing.
The tracking in german seems to be more detailed. I can see that it will be delivered tomorrow.
