My DM has been with Sky for ages. I convinced her to switch as the call costs were very high and she has signed up to EE with calls included. She has cancelled the DD to Sky. Is that right- is she not meant to tell them she is cancelling? I asked and she said there is no number or email and you can't contact them at all. Surely there is an easy way to tell them you are leaving. What happens if you don't?
