Internet in Germany (2)

The procedure continues as follows:
The next day, the provider calls you again, saying that they have received a call from the monopolist company: the rescheduled date, in one week's time, is too early, they can't make it. It will be in two weeks after all. And indeed, a few days later, you receive a letter from the provider, informing you that the earlier appointment unfortunately did not work out as planned, but that, in order for the connection to work, someone really needs to come and install the whole thing, and that hence, a new date has been scheduled, which is about a week from the time at which you receive the letter. You appreciate their informativeness, although you think quietly by yourself that a little less information in exchange for a little more speed and efficiency would not be a bad deal.

Interesting note: the provider sends its letters through another company than the good old Deutsche Post, which was the reason the first letters were delayed rather severely. This time, however, the other company seems to have found my mailbox: the most recent letter was not delivered by DP. This was not the only change: the lid, which normally closes the mailbox, was sticking out, like a letter that didn't completely fit into the mailbox.
Apparently, the other company's mailmen are new to the job and, having figured out how to deliver letters to mailboxes without name (but with number), are now working on the next step: delivering mail to mailboxes without taking out the door first...
(It was quite easy to put it back in, I found to my relief.)
