That's great. Netherland banned them a couple of years ago. Unfortunately I still receive them. Sometimes a lot. A year or two ago, I received calls almost every week from a major TV/internet provider (Ziggo-Vodafone; total crooks). I told them not to call me again, I complained to the regulator, but as far as I can tell, nothing was ever done about it.

So banning it is great, but you still need to enforce that law.
