I have had 3 failures this year sending registered mail to Germany.
It is not possible to track them once they leave the UK.
I presume the system DHL use is not compatible with most mail systems tracers.
This only seems to have happened since privatisation.
The worst 2 instances one parcel was returned after 3 months and the other containing a one off model claimed to have been delivered after 3 months to the PO box addressed to despite the fact it was addressed to a house.
The model was never returned.
I no longer use German tracked mail and send parcels by ordinary mail.
They do take a couple of weeks but so far they have all been delivered.
generally good although one package was returned to sender after 4-5 weeks with note UK NOT KNOWN ADDRESS???????????????
In mid-August I sent a Priority Flat Rate envelope with tracking and multiple copies of my naval model publications to my friend Niels, for his Groener naval publication group. As of today, it has never arrived.
Niels said German TV reported on how unreliable German mail was, with employees lowly paid and overworked. He has lost three mailings this year himself.
I wonder if other members on this forum have had mail problems with Germany, either sending or receiving.
