Deutsche Bank is massively worse than any of them for society and to most customers. Vonovia is a stain on society. No doubt there are many many worse companies for various reasons than the three you listed.
Deutsche Bahn is inefficient. But I have no idea why you consider them all that terrible. Deutsche Post isnt even all that bad. Theyre one of the best companies in the public package delivery space.
DHL is bad because they underpay their employees so in a large city, employees will dump their packages at the first door, very annoying if you life in a large house with many flats, you have to search for the person who took the parcel - even if you're there they will not ring the bell, just dump everything.
Deutsche Post next to me you usually wait 30+ minutes in a long line (dozens of people) with the unfriendliest employees possible, it has a 1.9 (!) rating on Google.
(I have no car) Deutsche Bahn is incompetent, trains cancelled, too late, wrong car order, non working climate control, 1st class car missing, restaurant closed and much much more.
Deutsche Telekom wouldn't activate fiber for nearly a year although everything was build and finished. Computer said no, no one wanted to come and see that everything is ready (they installed everything) because the computer was in an inconsistent state (20+ calls plus a lot of escalation worked after nearly a year of me paying 99EUR/month 5G for my remote work).
The others pay worse, then. DHL has by far the best delivery for me, closely followed by Amazon, then it’s UPS (though they are used so rarely, my samplesize is tiny), and finally DPD and GLS. Oh, and of course there is "roll the dice delivery" aka Hermes.
When complaining about the quality of the "former state railroad", the emphasis is on "former". The Deutsche Bahn offered much better services, more efficiently and at higher reliability, when it was still state-operated.
Telekom has always been bad, of course. To be fair, some of it is due to bad regulation, but they also just seem shockingly mismanaged.
This must be a joke! DPD (DPDgroup, or whatever) is borderline incompetent.
I'm on vacation, and I needed a laptop. It was shipped from Germany ... after sitting somewhere for days. Then no information for 4 days on their tracking site. Then more information but I never had even an approximate day they would attempt delivery (let alone a 2h slot).
Said laptop is now returning to Germany, because DPD couldn't be assed to inform me they had a local partner in the country I'm visiting, or collection points, and because their local partner (owned by DPD, so corporate separation is no excuse) didn't feel like attempting delivery more than once.
It's not like they couldn't contact me: they had my email + phone + cellphone. They just didn't try (no, there's no mail in the spam folder).
I left them message on their website multiple time - it never had any effect on the "ballad of the laptop".
I've heard it from other people before, but now that I've seen it myself, DPDgroup is so utterly efficient that in comparison even USPS is a paragon of virtue at every level.
also deutsche post... what's so bad about it?
I'm using Deutsche Bahn for 45+ years now. Before privatization trains were on time but employees thought they are managing a prision. Since privatization there are always problems. Late (they say 5min which means 10, they say 10 which means 15, they say 15 which means 30, they say 30 - it will never arrive). Trains are dirty, lots of ICE trains are old, you're very lucky when you get a new gen 4 train. Two weeks ago they had to vacate a railway car because the air conditioning broke down - everyone had to go to another railway car in an already full train. Which was a replacement ICE, because the the train I had a reservation for was cancelled. I was very lucky to be able to make another reservation in the next train, which was very full because of the cancelled train, and people were angry because they couldn't sit although they had paid for a reservation.
And they own the tracks so do everything to kneecap the competition. Some competitors that exist are much much better (e.g. ODEG).
The also had a legal monopoly on bus travel in Germany (fell after 70 years). And did everything bus travel was as unattractive as possible so people would use trains.
They have an app where you can check in. But only if you're going alone, if you travelling as a couple, you can't check in. We tried the app for some time and thought it was an UI problem or our stupidity, when a Deutsche Bahn employee confirmed that it's not possible to check in with two people sharing a ticket in one app. You need to buy two tickets - beware if you travel with two persons. As we say in Germany, #neuland.
And lastly, it's way, way, way too expensive. They are seriously charging 100 € for a 2 hour trip through one state when you don't book weeks in avance.
1. Deutsche Bahn (former state railroad)
2. Deutsche Telekom (former state telecom)
3. Deutsche Post (former state postal service)
What a coincidence.
