We've not had the e-mail service that we had before the change. They managed to give us the email address that they decided (username @sky.com - it only took them 6 days to make that one work) but not the one that we had before that is still getting messages and is still shown on our 'MySky' profile.
Almost 2 weeks on and I'm getting bored of waiting - I'll be asking for my MAC code soon, even though I'm still in the 1st 12 months I can't see how this is anything other than breach of contract by them. I pay over £80 a month to them on average so I've got some leverage there too.
It was bad enough had they imposed this change on us and it had worked (so much for customer choice) but it looks increasingly like they've used the "if you give an infinite number of baboons an infinite numbers of wires one of them will give you a working email" approach.
