I suppose an equivalent would be something like an internet connection to a house. There’s a 2-week cooling off period to change your mind, but you still have to pay for any service used up to that point - including the standard £60 (ish) Openreach engineer fee, if you’re going with a provider that doesn’t cover this upfront for you (many do nowadays, but some don’t and never have). You still received the service at the time, even though it later was effectively reversed, so it won’t be refunded.
