@O2 I'm on a new O2 plan,Unlimited Smoke Signals, 250 Carrier Pigeons a month & Free Messages in a Bottle to other O2 customers!

@O2 Any compensation for all those affected the last 2 days?

@O2 your going have to give your customers a lot to make up for this because you didnt evan tell the customers that the network was down

@O2 ..O2 uk user roaming at Netherlands. Voice calls are fine. but 3G is not working yet.

@O2 YAY

@O2 if you could hurry up we'd be grateful, have a full power cut at the minute, isnt going to be fixed for 2 days, have no means of contact

@O2 Hopefully we'll get a rebate this month for such a crappy service

@O2 I appear to have full service back - thank you!

@O2 Good, pleased to hear it. Now then, how are your customers going to be compensated, especially those of us on contract?

@O2 will I get any credit applied to my account due to the lack of service over the past 24 hours?

@O2 Cant you get it fixed sooner? I have not been able to use my phone since last night. This is a terrible service.

@O2 Oh is this a new problem because I never have signal from 8:30 to 5:30 everyday
