Change billing date
You can change your billing date here: account.viaplay.com/gb-en/changedate
You can only change the billing date to today’s date, e.g. if you want to move the billing date to the 25th of each month, you must make the change on the 25th. What happens then is that we end your current subscription and activate a new subscription.
You will then be charged for the coming month and also receive an automatic refund on your remaining days of your previously paid period.
