I don't know how things work in Germany specifically, but when I lived in England I was rather peeved by their TV license thing. The very first communications were full of threats and strong language, and pretty much demanded that I either need a TV license or declare that I don't have a TV (which I didn't). I didn't reply out of principle, as I don't think it should be my burden to prove that I don't use a service and I resented the implied accusations (British are really not as polite as the stereotype says – quite the opposite I found). After a few more threatening letters they said they would "open an investigation" shrug. I left the country before anything came of that.
