Does all data go back into the bank including the extra data I used if it doesn’t get used

So I didn't know how to word the question,

basically at this moment in time 1/10/2024 my wifi internet is down so I have added data using my sky piggy bank just to make sure I don't run out before it is fixed, and I was wondering if the extra data that I added will go back into the piggy bank if it isn't used by the time my data refreshes

Yes.  Say you move 5GB across but only use 3 then the unused 2 moves back to your bank at the end of the billing period.

Short answer is yes. All unused data will return to the Piggybank.
