genie, I have had 1st hand experience of this today, there is no way to change your package at the moment except by guile. They claim you can do it on the site but when you try it says you have to call, when you call it says you have to be one of the key workers. Here's what I did, I followed the complaints path, once you get to the bit where they let you email, you say all the above then threaten to cancel the DD and move to virgin unless they call you back. They called me back within 30mins. I got the changes I wanted including the new package (which also includes Netflix). This is what I wrote:
//Account Number: N
Viewing Card : N
Hi, I need to make changes to my TV package etc but currently you appear to have no way of doing what I want.
When I phone I am told do what I need on sky.com but when I do, it tells me to call 0333 757 3772, and that tells me I'm not a priority.
Can someone call me back within 7 days or I will be forced to cancel my DD and move to Virgin.
thanks
