    I am having an absolute nightmare with @ThreeUKSupport since November! Attempted to upgrade, new phone was recalled by three as they were unable to speak to me on my broken phone. Decided to cancel contract and upgrade with @O2 but now three are trying to charge me £700...

  • writingabit Rachel (@writingabit) reported

    @O2 The SE2020. I do actually have an iPhone plug but I wasn’t impressed. I probably will cancel the upgrade anyhow, if I can work out how.

    @O2 The phone has some signal, just doesn't want to call out. I completed the Sim swap using the new sim provided Saturday evening & followed the steps on the phone.
