I believe you have a 14 day window if you change your mind to revert back to your original package.
Got a query with your contract or wish to cancel? You can speak to our team on 0345 234 0754* anytime Monday to Friday; 8am to 8pm on Saturdays; and 9am to 5pm on Sundays and Bank Holidays. Please have your account number (which you can find at the top of this contract) to hand. To cancel you have FOURTEEN days from the later of: (i) the day after the delivery of the equipment; (ii) the service start date; or (iii) the day you received this contract (that provides a link to the Terms and Conditions).
You might want to keep this current package and add a personal pick to restore the missing channels, however that would be an extra £10pm for the first pick, and an additional £7pm for any subsequent picks.
