Discounts expired, if you've been with Sky for a while?

Could any of your previously discounted deals have expired? You would have been notified of their end date when you first took them out but at present you don’t get reminders prior to them ending. You could compare a previous bill to your latest bill and see where the amounts differ.
If the discounts have ended you will need to contact Sky to try to negotiate a new deal which will require another minimum term contract, although Sky are not obliged to offer you another discount. If you sort something to your satisfaction make a note of the date it’s ending.
You can either call Sky or use the following link https://www.sky.com/help/articles/cancel-sky-tv#contact-leave
