    @Jewkneeor @O2 @VodafoneUK Honestly terrible service here I think it’ll be EE or 3 from the look of it when I go to change provider at the end of my contract

  • internetsense Philip I Wilson (@internetsense) reported from Belfast, Northern Ireland

    @LauraJ2803 @SarahSherry1 @O2 This is criminal activity I was charged £2 per day by #Three Which is bad enough Truth is like petrol/oil/electric/tv you can't change as they're all at it!

  • 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.

  • 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 🙈🙈🙈

  • rickgwalker Richard Walker (@rickgwalker) reported from Whiteabbey, Northern Ireland

  • 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

  • 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.

  • PcConlon P Conlon PC (@PcConlon) reported from Belfast, Northern Ireland

    @DPDgroup_news @O2 your service is a joke

  • ScottD_DJMS Scott Dixon (@ScottD_DJMS) reported from Belfast, Northern Ireland

    @O2 @virginmedia still unable to sign in to the Priority app using virgin. Any advice or update please?

  • 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.

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

    @O2 I won an instant prize from Greggs but no voucher appeared, can you help?

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

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

  • roryg2009 Rory Gallagher (@roryg2009) reported from Belfast, Northern Ireland

    @o2 I resorted to emailing the CEO today @LutzSchueler because no one will help me with refunding me for an order I cancelled and didn't receive...

  • DAVIDBUZZ2904 DAVIDBUZZ2904 (@DAVIDBUZZ2904) reported from Lisburn, Northern Ireland

  • 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

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • GunnComics Jay Gunn (@GunnComics) reported

    Word of warning for anyone using @O2 . Had my contract originally with Orange 20 years ago and then it was bought out by O2. Phone no longer works and is now proving impossible to close down the account despite giving ID such as bank details, passport and other ID.

  • kiddakowalski JL (@kiddakowalski) reported

    @LeeFMc83 @O2 Common problem in all service industries now. No one takes responsibility, always another department, 3rd party or the old favourite 'computer system'. Just an excuse to hide behind doing a bad job.

  • GunnComics Jay Gunn (@GunnComics) reported

    @FraserC69 @O2 I am genuinely absolutely appalled at them, deeply shocking customer services to be told by them to refuse to leave a store until my contract is cancelled. It’s like something the BBC should be reporting on.

  • meatloaf_efc DT (Meatloaf) (@meatloaf_efc) reported

    What is going on with @O2 signal at the mo? Been so reliable but now drops out whilst standing still

  • LveLuvLeo Leo (@LveLuvLeo) reported

    @O2 So you can’t advise me on your mast not working in LS8??? And when it will be fixed?

  • edmondssss baby j (@edmondssss) reported

    @O2 text messages wont send, my 4G is so bad and wont connect and its so annoying 😭😭😭

  • SirGawaine1 Gavin Barber (@SirGawaine1) reported

    @O2 How do I unlock my device when you’ve already pulled my service?

  • meatloaf_efc DT (Meatloaf) (@meatloaf_efc) reported from Gobowen, England

    Hi @O2 can you please tell me why my signal keeps dropping out? Even when I'm standing still it will just drop even though phone says I have signal. Cheers 👍

  • ElsaHTwit Elsa (@ElsaHTwit) reported

    @O2 Hi I tried on different browsers and devices, can’t seem to log in to my account. Would you be able to check if there is an issue with my account?

  • Toffeelewl Lewis Hughes (@Toffeelewl) reported

    @LeeFMc83 @O2 Have you rung the depot mate? These phone companies always seem to do the absolute minimum. Either that or cancel and go walk into a store with stock from another network? #coolingoffperiod
