  • salexander835 Stuart A (@salexander835) reported from Holywood, Northern Ireland

    @O2 I can't get logged into my account through the app or via the Web. Is there an issue?

  • kkanecelt kierankane (@kkanecelt) reported from Belfast, Northern Ireland

    @o2 is the worst shittiest network I've ever been on in my life

  • EmGymMum Em (@EmGymMum) reported from Belfast, Northern Ireland

    @O2 @KLogan1977 Update: So @O2 asked me to DM details of the issue. I sent it hours ago, yet still no response. I wonder if there is an intention to help or it is an illusion of good customer service. Nor have I got promised call back after 22 hours from the CS phoneline. Not good!!

  • BrendanB2 Brendan Bonner (@BrendanB2) reported from Belfast, Northern Ireland

    @O2 I wouldn’t recommend anyone buying online and redeeming your phone. Go to the store, you can’t trust any of the online and virtual services. Was a handling getting phone set up, getting help and they only give you 50% of the value they say (no matter how good your phone is).

  • liznangel3 Liz Cullinane (@liznangel3) reported from Balmoral, Northern Ireland

    @EmmandJDeSouza Burnfoot, Donegal house in Derry UK Workshop Donegal, Irl @O2 flicking from roaming to home constantly, useless turning it off roaming I'd never get any work done👿

  • McGuinnessKevin Kevin McGuinness (@McGuinnessKevin) reported from Belfast, Northern Ireland

    @o2 any chance you can sort out the masts in Belfast.. really slow connections and dropped connections, I’m even with o2 (was with you when it was BT Cellnet) I’m with sky who use your network but I know of o2 customers having the same issues. #o2network

  • billyjatkins billy (@billyjatkins) reported from Belfast, Northern Ireland

    @seanp280 @O2 Where are you in Belfast? I live beside city hospital and I get full bars all over the city, 5G too! Only when I venture into the depths of County Down does it deteriorate lol

  • 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.

  • UberGeekFanboy Fanboy (@UberGeekFanboy) reported from Belfast, Northern Ireland

    @O2 trying to phone through to return a phone and keep getting cut off? Wtf.

  • apallan ANN P V ALLAN (@apallan) reported from Belfast, Northern Ireland

    @Girlzmum Very poor service from @O2 especially to a front line worker in the NHS #NHS who needs her phone.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Belfast, Northern Ireland

    @O2 you guys got a number to your payments team? I need to speak to someone. Automated IVR is poor.

  • AskkeithInfo askkeith.info (@AskkeithInfo) reported from Castlereagh, Northern Ireland

  • JeremyAdamsNI Jeremy Adams (@JeremyAdamsNI) reported from Belfast, Northern Ireland

    @O2 AirPods and 🎅 is looking after them! Again fantastic service.

  • 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.

  • columcoyle Colum Coyle (@columcoyle) reported from Castlereagh, Northern Ireland

    @angelcosta78 @DPDgroup_news @O2 @AppleSupport Just checked and its now saying the same for me! Apparently it takes a full 26 hours to get from Birmingham to Down 🙄

  • JeremyAdamsNI Jeremy Adams (@JeremyAdamsNI) reported from Belfast, Northern Ireland

    Great customer service @O2. Placed an online order at 6.30pm last night and arrived 4.45pm in Belfast.

  • columcoyle Colum Coyle (@columcoyle) reported from Castlereagh, Northern Ireland

    @angelcosta78 @DPDgroup_news @O2 @AppleSupport I’ve sent a complaint to O2 asking for a refund of the three days I’m missing out on my device plan. They’ve already charged me!

  • thebaldfather Hugh Pollock (@thebaldfather) reported from Belfast, Northern Ireland

    @O2 I am amazed by the lack of support from your network. Trying for a week now to get help and your help and advice is pathetic when you eventually answer.

    @Abibradley13 I've always been happy with @O2 . Aside from the odd loss of signal in remote places I can't recall having any issues really.

  • improvemydiet Arelis Rodriguez, RD 🕷🇬🇧 🇪🇺 (@improvemydiet) reported

    @actionfrauduk @HSBC_UK @O2 Thank you very much. I have never clicked on any links. I always report to O2 and block sender but messages keep coming through.

    @O2 hey there just a quick concern when you eventually merge with @virginmedia will I have to change to a virgin media sim or will O2 as a company/network still exist

  • jiteshgopinath ethanhunt27 (@jiteshgopinath) reported

    @ThreeUKSupport have you noticed that your app keeps on asking for an address every time we use the app to recharge . It connects to some pathetic web page that keeps on asking for details even if its our account. I use @O2 @EE sims as well and I have no problems recharging these cards.

  • special_dfo DFO (@special_dfo) reported

    @O2 unable to log into My02 account. Page doesn’t load. Tried App and Desktop. Is your website down? Losing patience fast.
