    @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.

    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

    @O2 hi. My friend’s UK mob stolen in Dublin. Need to cancel/freeze fone account. Help!!

  • 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?

    @O2 your service coverage is dire, you used to be the best around Wellington TA21 9 but it is now pretty much unusable! Time to change I think 🤔

  • chelleskirby che!!e (@chelleskirby) reported

    @O2 are ******* stupid

  • Lucidavis86 Lucinda (@Lucidavis86) reported

    Hi @O2 - have you changed the software you use for your online chat? It's awful and a bit of a step backwards 🙄

  • RockLobster6 Rach 🐀 (@RockLobster6) reported

    Hey @O2 why do you hate the county of Greater Manchester so much?? Why are we not allowed reliable signal even when you charge ridiculous prices???

  • join4te Jay (@join4te) reported

    @O2 Day 68 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.

  • thedogger31 darren (@thedogger31) reported

    @O2 Problem is all the tips in the world won’t help if the signal is poor or non existent

  • AbbieRoseSmith Abbie Smith (@AbbieRoseSmith) reported

    @O2 does anyone answer your customer emails, 6 days and counting

  • 15thpromotion 15thpromotion (@15thpromotion) reported

    @O2 It's been more than a month still no reply from you guys on my issue?

  • adamskiodp Adamskiodp (@adamskiodp) reported

    @O2 Hi, how does O2 normally inform its users of any planned maintenance on the network? How do O2 customers know in advance if their local mast(s) will be out of action for a period?

  • HAALAND_ERA Tom (@HAALAND_ERA) reported

    @O2 is o2 down ?
