The most baffling thing here is how the hell did the author get the organisation to respond, on topic, multiple times? In my experience conversing with various entities that are supposed to provide customer support, absolutely anything outside of an extremely narrow set of vetted topics with prepared answers and especially anything technical gets ignored and receives an irrelevant response at best.

I am assuming because the BBC is a government organization? I am not sure about the UK but where I come from the government is legally required to answer your request. They have to. Doesn't mean they'll answer your question but they'll answer something. (plus they have to confirm reception/delivery and stuff like that)
