Oh. You have never dealt with the German company T-Com?
Practically Monopolist, still having many habits of the federal mail service. When your telephone does not work, they offer you to send a technician ASAP.
This means: You get a day. On this day, somewhere between 8:00 and 16:00 the technician will come and fix your stuff. Or will not come. Or will come, ring once and if you don't open the door in 33.5 seconds, drop an already prepared complaint about your absence into your mailbox and runs away. The next appointment will be in 3 weeks or so. Of course, according to the same rules... somewhere between 8 and 16, or not at all...
You think, Dell is terrible? You have not seen Germanies former bureaucrats yet...
Even worse had been the experience of a friend. He changed his phone and Internet contract to a flat rate payment. A few weeks later, he got a bill over a few thousand €. They billed his own contract (per minute), the flat rate and some oscure extra bill. Instead of realizing that they did something wrong (they billed twice for the same service - illegal in Germany), they insisted on being right. And in the moment my friend called a lawyer and sued the T-com, they cut his telephone - he was without phone for two months (until a new companies was found and was able to connect him, because the T-Com is not willed loosing customers).
Not too bad for him, he can survive this. But his friend works as independent mid wife and needed the phone for earning money...
