So O2 haven't exactly been the most reliable network over the last couple days.  A huge amount of customers have been affected by the network outages across the country, so many have taken to Twitter to vent their anger.  Luckily, the in-house social media team of @O2 were waiting, with some rather hilarious responses.

@grahamcummings7 Maybe later, got tweets to send right now.
