O2 4G working again: Here's what to do about complaints and compensation if you were affected

O2's 4G is finally working again, after people were left for almost a full day without internet. Plenty of people are using their newly restored internet connections to vent about the outage, and to try and secure some compensation for the day spent without any data at all. The outage caused issues not only for people rushing to catch up on social networks. Many rely on their data connections for important healthcare or other uses, and the lack of data even meant that bus timetables and other important infrastructure stopped working properly. Amid that frustration, many have asked whether it will be possible to claim compensation or at least some form of redress for the problems, to make up for the frustration.
