Considering cancelling Sky Q but have a few questions

Hi. This is a little complicated but here goes... I signed up to Sky Q in the summer of 2017 for the Sports channels package but was told that package was an "add-on" package and that if i wanted it then i would need to be subscribed to another package first. So i chose the Variety channels package. I was subscribed to both of those packages for the next 18 months. When i called up to remove the Variety package after the minimum contract term ended (i was finding paying for both packages a little expensive and i rarely watched any of the channels from the Variety package) i was told that this would not be possible and as long as i still wanted the sports package then i would also need to be subscribed to another package at the same time. So i have considered just viewing the sports channels through Now TV instead (why didn't i think of that before getting Sky Q? :rotfl:) Anyway, i understand that if i do cancel Sky Q that they will ask me to return the Sky Q box within 30-60 days, but i want to keep it in-case i decide to rejoin sky q at a later time (plus i have a lot of programmes recorded on there) My questions are: 1) If i decided not to return the box, is there a one-time charge for not returning it? and 2) I understand that after cancellation while i am no longer a subscriber, i will not be able to view any of the recordings on my sky q box, but what if i kept the box and re-joined sky q again at a later time? Would i then be able to access and view the recordings i had on my sky q box before i cancelled my subscriptions? I am grateful for any advice about this.
