Hi SilverFox,
It looks like you're eligible for a Value Pack discount, but aren't getting it - the package you're on qualifies for an £8.50 saving, meaning you should be paying £53.99 per month instead of £62.49. If you call Customer Services (0800 052 2000, Option 5) and ask them to check, they should be able to add the Value Pack discount on for you.
Alternatively, for an extra £4.50 (so, a total of £58.49 - still less than you're paying now), you could get 2Mb broadband if you call Sales (0800 183 1234) and ask for the "Talk Unlimited, 2Mb and Family TV Value Pack", with the phone line upgraded to Talk Unlimited 24.
