This is a customer forum, never expect to receive a reply from Now TV staff.
And by service, are you referring to broadband? Or TV passes such as Entertainment or Movies?
Either way pop onto Live chat for all TV related queries. There is a broadband phone number you can call, but that is ONLY for broadband and they will direct you to Live chat for TV related issues.
