Sorry!
I think Packeta does not do business in Germany, at least not under this name.
I figure Trezor gives the packet to Packeta, Packeta gives it to Hermes in Germany, Hermes transports it to the Hermes pick-up point where I picked it up.
The nice side effect in my case was that the sender shown on the packet that I picked up in the Hermes pick-up point was not SatoshiLabs but Packeta.
OK, now I understand what you mean.
They have an official website for Germany here >
https://www.packeta.de/. It says that they have over 16,000 pick-up points. At the same time, they also have close to 190,000 partner pick-up points. Hermes transports might be one of them, depending on the region and city. 16,000 locations might sound like a lot at first, but it isn't really. Especially if you live in a smaller town.
