Can't find an obvious pagein the f2s site about terminating the service with them when I migrate away. I move to o2 on the 19th and I'm just on a rolling 1month contract so I'm assuming (probably wrongly) that it'll automatically cease on that date and I don['t need todo anything ? 
Never migrated before so I'm new to this - I joined f2s way back in 2002 being my first provider.
