I've just moved house.
Being a wimp law abiding citizen, I not only pay for a TV licence but I let them know where I am and therefore what property the £12.82 I pay them every month is to cover. So I've done an online change of address. Fairly basic stuff?
So why did it cost me £16.50 to give them this information? None of my other utility suppliers charge me for communicating with them.
YANBU - the BBC should be sufficiently grateful for your monthly contributions to want to know quite what you're paying for.
YABU - the BBC is a sacred cow who make up their own rules.
