Just a note to keep hold of the Sky hub if you cancel, and aren't asked to return it straight away.
I received a text this morning saying my returns packaging is on its way. I cancelled as of 4 October last year, almost seven months ago, so was surprised to receive this text after such a period [I cancelled broadband but not TV].
Fortunately I have kept it, so am in a position to return, but I'm sure many people wouldn't have for such a period.
