    @JohnBirtwistle @O2 Atrocious. Unlike other companies who take a DD payment out on Fri or Mon either side of a weekend due date, O2 don't do that, they suspend outgoing calls, demand payment & threaten to cut the user off! They claim it's a system error but do nowt to fix it, as it keeps happening!
