I would just say on the matter you brought up - advertising.
Being not far south of Brum I was amazed that I never saw a single advert for DUO. No the TV, nor the radio, nor the billboards, nor the buses. Nothing, nadda, nilch.
I used to think Go spent far too much money on plastering themselves all over London. I guess now I see why.
Good luck to all those hit by this, stress, worry, misery, I wouldn't wish it on my worst enemy.
