I've joined TalkTalk for phone & broadband and they've organised engineer for 21st December. They told me to cancel Sky which I did. Told by Sky 14 days notice for phone and 30 days notice for TV. This was 2 weeks ago. Still have phone and broadband. Went to chat to Sky advisor and both phone and TV are due to stop on 26th December. Will the engineer still be able to switch over to TalkTalk on 21st December?
