My hub 3 was replaced with a hub 5.
I have a big box with a returns label, and I am sure I read it should be used if I am emailed to return something, although I cant seem to find that.
The Hub 3 doesn't fit very well in the box, although with a bit of padding it should be ok.
Anyway do virgin want hub 3s back, and if so do I just return it, or should I be waiting for an email with instructions etc?
