    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

  • skbarrone Sarah Barron (@skbarrone) reported from Fingal County, Leinster

    @O2 Thanks. Problem started in London but same in Dublin. Everything works fine on Wi-Fi.

  • JadeWatton Jade Watton (Taylor's Version) ❤️🧣🎀 (@JadeWatton) reported

    Hi @O2 I have been waiting for 2 weeks for a reply email from O2 complaints, with the issue going on for months.

  • dickfleur1 richard (@dickfleur1) reported

    @O2 why does my phone say I have full 4G yet I might as well have no signal at all, I looked on your site and it give me some BS about spectrum, I live in an area with a few villages and a small town, not alot of people. How can you justify charging so much for unlimited data

  • HowardYLAPE Howard Lee 🇺🇦 (@HowardYLAPE) reported

    @O2 It's now 2nd week down, only working sat/sun. My parents have been unable to do online banking (requires callback) , no texts etc etc. They are 80 & 100. Their phone/SIM don't do Wi-Fi calling and even if it did they're pensioners not techies.

  • cjmr1988 Carly (@cjmr1988) reported

  • HayleyC1983 Hayley Betts (@HayleyC1983) reported

    @O2 Incompetent customer service that’s what. Is someone going to contact me to resolve my complaint?

  • Outdoorsy_Chris Chris (@Outdoorsy_Chris) reported

    @O2 How do I make a formal complaint. It’s absolutely shocking the quality of your network. Daughter on EE, no issues, Son on Vodaphone, no issues. Wife and I with full signal on 4G, unusable.

  • little_lea16 Lea 🇬🇧 🌹💞 (@little_lea16) reported

    @O2 I want to cancel my 30 day plan sim with yourselves. I don't want to wait hours on hold on the phone. I'm fed up of the monthly charges secretly increasing, without any notice, despite being on unlimited! I can get a cheaper deal elsewhere!

  • tracestarshine Tracy Allan (@tracestarshine) reported

    Appalling customer service from both @dhlexpressuk and @O2. Phone addressed to and delivered to wrong address. Signed for by DHL driver himself. Deliver to an unoccupied house!!! Nobody calling me back to resolve the situation. What do I do now??? @O2 what do I do now??

  • EgalGeordie Egalitarian Geordie (@EgalGeordie) reported
