  • adammccalden Adam McCalden (@adammccalden) reported from Belfast, Northern Ireland

    @virginmedia since my virgin mobile UK signal has been shifted from piggyback Vodafone to @O2 it has been a complete disaster, constant signal dropping, constant WiFi calling cutting. This is before my account has been transferred to O2. Complete and utter rubbish

  • SamCamLlamClam Samantha G (@SamCamLlamClam) reported from Greenisland, Northern Ireland

    @O2 repeatedly ignored by your dms.. been trying to contact you for days - I am incredibly distressed and humiliated by this treatment. Quick enough to get in contact when you want someone to sign up.. not so much when someone wants to cancel their account. Sort it out.

  • irishangel84 Shauna (@irishangel84) reported from Belfast, Northern Ireland

    @O2 Don't care about Peter Kay tickets but I can't even get my Friday Greggs treat 🙈🙈🙈

  • 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.

    @DPDgroup_news @O2 your service is a joke

  • 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 is there any way to arrange a call back over Twitter for the fraud team? My mothers been waiting a month now for a call back with her o2 account still locked out, she’s called dozens of times promised call backs and she’s never called she’s still on hold and fraud closes at 6

  • 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

    Oh my good god why is O2 customer service so ****? @O2

  • adamwingie Adam Breen (@adamwingie) reported

    @O2 Of course I have Wi-Fi. That doesn’t help the fact I pay o2 a large amount of money every month for a service that they aren’t providing.

  • HarrietWittmann Harriet Wittmann (@HarrietWittmann) reported

    @O2 For the past two weeks I haven’t been able to get my free Nero coffee. Don’t say “there is limited stock try again the next day” which seems to be your standard reply to everyone that has been asking the same thing. It has never said out of stock before these last 2 weeks.

  • kellyappleton82 Kelly appleton (@kellyappleton82) reported

    @O2 I've just ordered a new phone and didn't realise it didn't come with a charger. I've looked at your accessories which say you can get 30% off a charger if ordered with a phone. I never got offered this during the upgrade process,can you help?

  • realDavidMyers David Myers (@realDavidMyers) reported

    @AmeliaNFFC @O2 I’m now on the phone to them to cancel my contract

  • ProfCTurner Professor Colin Turner (@ProfCTurner) reported

    @adamwingie @O2 I've just upgraded my phone on @o2 in the last couple of days. Despite the coverage charts saying there's no 5G where I am (Bangor), there is but the upload speed is so slow as to be literally unusable.
