haven't had a problem?
Wow you are lucky. I don't have a TV anymore, nor devices for watching. I get a letter every other week (which I save and deliver to my MP). I get a visit around once a month (which I refuse to let in my house). Eventually they will get tired of the game and turn up with some court order I expect.
This is intimidation. If I were a little old pensioner instead of being a bloody minded miserable grumpy old man then I might be scared into all sorts.
In the UK we are supposed (and I know it is now very clearly no longer the case) we are supposed to be innocent until proven guilty. It is up 'to them' to build a case and prove you are guilty of an offence, it is NOT up to you to prove yourself innocent.
I expect we will soon see the day when MPs back down and allow the BBC to charge us all regardless of whether we have any means of viewing tv. They will argue that the bbc provides online stuff for everyone and therefore is allowed the money. This will lead to situations like the one in Germany where a guy with no power never mind tv in a shack in a forest clearing has to have a licence.
Frankly I would prefer the MPs dismantle the bbc and let it go to a warm place in a handcart
