  • TheRealJackieJ Jackie Johnston (@TheRealJackieJ) reported from Castlereagh, Northern Ireland

    @O2 Thanks. How do we unsubscribe from this ****? We pay for 5 contracts and do not wish to receive these messages particularly on children’s phones.

  • GeorgeCowan Britishgamerni 🇬🇧🏳️‍🌈 (@GeorgeCowan) reported from Newtownards, Northern Ireland

    @O2 Yeah that doesn’t give any way to report an issue or anything not helpful

  • Watsonmydear Christine #StaySafe #SaveLives Watson 💙 (@Watsonmydear) reported from Belfast, Northern Ireland

    💡 check your Tesco clubcard account - vouchers for restaurants, Denby dining sets & more - I’ve enjoyed 3 course meals for 2 for like £1.13! 💡 check your topcashback account could be £££ for a M&S voucher for example 💡 If @O2 customer make sure you download free priority app

  • RunRosyRyanRun Bacon From Heaven (@RunRosyRyanRun) reported from Belfast, Northern Ireland

  • IanRobinson Ian Robinson (@IanRobinson) reported from Dundonald, Northern Ireland

    Is a cellular Apple Watch looked to the network provider you get it from? I have a Stainless Steel Series 6 that I got from @O2 that I no longer need since I got my Ultra from O2.

  • catherine271076 Catherine Dwyer (@catherine271076) reported from Jordanstown, Northern Ireland

    @O2 I need to escalate a complaint re. a member of staff who refuses to to 1) process my upgrade and 2) who has just terminated my call. Who can I talk to? Your staff say it’s not possible to talk to a manager.

  • GarethAJMiller Gareth (@GarethAJMiller) reported from Belfast, Northern Ireland

    @O2 how can I get in touch about my last bill? Recently left o2 so not letting me start a live chat as I can’t login

  • IanRobinson Ian Robinson (@IanRobinson) reported from Stormont, Northern Ireland

    @chriswb @O2 No. Plus it says No Service where the O2 logo should be. I might try the SIM in my O2 iPhone.

  • welshmantom paul johnson (@welshmantom) reported

    @O2 Absolutely shocking company now who fail to deliver. If it's not an appalling signal across the UK it's a useless priority app that crashes under the slightest pressure and when you complain, they fail to communicate, reply,which sums up how bad they are.

  • big_ph1l Phil (@big_ph1l) reported

    @O2 im having a horrible time with yourself atm , trying to get a phone out on contract amd the advisor keeps hanging up ! Very annoying

  • JohnnyGaluva Johnny Galuva (@JohnnyGaluva) reported

    The amount of SMS spam I receive on my GiffGaff iPhone these days is ridiculous. Several per day. You'd think @giffgaff and @O2 would have proper spam filters on their network.

  • RaeRubyRaeK RaeRubyRae (@RaeRubyRaeK) reported

    @O2 I went to my friends house to use her iPad & still the same, so it’s not my phone, not my broadband, iOS or anything else, it’s a YOU as in o2 are crap problem. After my current contract ends next year, which will mark THIRTY-FIVE years as an o2 customer I’ll be leaving! 😤

  • RaeRubyRaeK RaeRubyRae (@RaeRubyRaeK) reported

    @O2 All of a sudden because I tell you I’m leaving after nearly 35 years you actually want to fix a problem? Too little too late! 😤😤

  • Stephen1970t StephenTHFC 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧🇮🇱🐓🏆 (@Stephen1970t) reported

    My new phone still not working after 3 days because my eSIM can’t be updated on my account. Can’t transfer my number over. Pathetic @O2

  • LMDX01 Ash Richardson (@LMDX01) reported

    @O2 10 times I have tried getting in to my account to pay my bill and it keeps getting me to verify my email when I do it keeps taking me back lose the **** with virgin or don't expect me to pay whilst that **** is happening sort it out

  • stevepluta Steve Pluta (@stevepluta) reported

    @O2 @swantiquescouk If it’s the Greggs on the a1 it’s a franchise store and they have never worked there. You know this o2……

  • Newwicket newwicket (@Newwicket) reported

    @O2 eSIM upgrade for cheaper contract. Service assistants have not issued documentation and now I’m without service. I can’t call 202 of course and the nearest store is not convenient to get to.

  • dizsaidwhat Darren (@dizsaidwhat) reported

    @O2 your complaints team finally called today but only one belled then left a voice mail at 1315 saying they'd call back within the hour, it's not 1650 and no call back. It's been 9 weeks and no resolution for a very simple complaint.
