Change Sky Hub Delivery Date

[Atlas2]

My Sky Broadband activation date is the 6th of August. I won't be living in my new place until the 9th of August. How can I change the activation date, as well as, the delivery date for the sky hub?

@Atlas2  Royal Mail attempt to deliver the package and you should then be able to pick it up from the local delivery office if you miss them as they hold it for a period of time.
