This might help to explain it:

It sounds like the minimum term on your package has come to and end so the discount you had has now finished. When you took this out you would have been told how long it was going to last for so now is the time to call Sky to see if they will offer you a further discount for the next 24 months if you agree to a new contract.
If you have a Sky Mobile or Sky Talk landline phone then you can call Sky for free via the 150 number. Or under "Need more help ?" at the bottom this page is the number to call:
