Internet in Germany

It works as follows:

First, you go to several providers, and find out that apparently the best deal, even if you only want an internet connection, is something involving internet and telephone, costing about 50 euros a month, with a connection of 6 Mbit/s, i.e. 600 kb/s. Rather disappointed, you decide to do it anyway, and share the connection with a few people in your dorm to keep it manageable.
Then, you sign a contract, and hear that within two weeks, someone, from another company, as that company apparently owns the cable network, should come to install the whole thing in your room. You wait for two weeks, but nothing happens; no promised letters with exact date and time, no username and password, no technicians, nothing. You go back to the shop and ask what has gone wrong, and you hear that the next day, the technician should come; the letters have been delayed a bit but should also be there in a matter of one or two days.
The next day, no-one shows up, and still no letters. You go back to the shop, and ask again; they tell you that, apparently, something went wrong, and you will get a new date and time for the technician to come. You indeed get this date, in a letter, a week later, when also the old letters arrive; the new date is still a week later, all in all a month after signing the contract.
The day comes, but the technician doesn't. Calling the provider again to complain results in them starting an 'emergency procedure': someone should come in two or three days. Of course still no-one comes, or calls, or gives any sign of life, let alone of connection. You go back once more, to ask how this procedure is supposed to function if the people still aren't coming.
Then, to your great surprise, you find a note in your mailbox, from the monopolist cable-owning company, four days after the appointed date and time, saying that someone was there, but unfortunately could not reach you by phone or in person. Not that you have received any calls; you have not even been notified that someone would come at all. You call the company, and ask what this means; they tell you they didn't know anyone was coming, either, since the technician is employed by the monopolist.
They say that you have to call their customer service, through which you will be able to make an appointment with a technician of their own. Slightly surprised that now, they do appear to have technicians, you call the customer service, and they tell you to contact your landlord, because something in your room is still missing. You contact the landlord, who says that this particular item is provided by the provider. You call the provider again, and they suddenly inform you that a visit by a technician is scheduled in two weeks' time.
Rather angry by now, you go to the shop and tell them to do something about this. The people in the shop, who by now are getting tired of the whole episode as well, do their best, but don't get anything done at the moment. They promise to keep working on it, and later that day, you get a call from someone else in the company, saying that the appointment has been rescheduled to a week earlier, so in one week's time.

... and that's the point to which I've gotten in the procedure; I'm curious how it will continue. I always thought of Germany as an overly civilised and organised country, where the maxim 'pacta sunt servanda' is holy. But apparently, that belongs to the old-fashioned Germany, and not to the new, fresh, modern country where people have internet access...
