Dear Miss Hall,
Thank you for your email in regards to the issues you are having with your Sky equipment and viewing.
Please firstly accept my apology for the inconvenience and stress this may have caused you you and please be assured I will do my best to resolve this for you.
I have activated both cards and resent signals so could you please advise if you have received your viewing by replying to this email.
The issue with this was that the signals were not getting to your card so this is why you have had no viewing.
Kind regards
Caroline
