New Hub, Confused With Old

[Ribose]

Just upgraded to new hub via the email that was sent out, but I am confused with what to do with the old hub as there's multiple things I "have" to do.

Options given on different pages:=

1. Send it back straight away in the new packaging.

2. I keep it until Sky ask for it back via email at a later date (why later date?)

3. I don't send it back/keep it.

What would be the best thing to do?

Thanks in advance.

I have changed mine as well via the same emai and I sent mine back, it is clear of they want these back of not do to conflicting information but when ordering it, it did say to return the old so as it doesn't cost a penny this is what I did. Make sure you keep the proof of posting for at least 6 months.
