Every TV Licence letter we had in 2024

We have been legally licence free since 2018, we have told tv licence we don't require a one but they seem to think otherwise, we have the basic Netflix package £4.99 a month which works out to £60 a year £109 cheaper than a tv licence and far better value, we do not watch live tv or bbc i-player, 18 months into our no licence declaration they started to send us letters trying to get us to go on their website and fill in a form, as far as I was concerned we had given them all the information they needed in the letter we had sent in 2018 when we cancelled so we have ignored the letters ever since, I have lost count of how many investigations they claim to have opened but to this day they have never called at our address they just send a stupid letter every month, how scary is that !
