    @O2 Hi having problems making and receiving phone calls on a IPhone SE #O2

  • 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!!

  • 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

  • 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.

  • 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!

  • 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.

  • 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.

  • 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?

  • 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.

  • 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

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

  • 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.

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

    @O2 Reece in your forestside store was a legend I ran through door cut off from world and all sorted for phone and lap top in 12 mins a credit to public service he’ll be snapped up by someone soon give him a pay rise and pat on back

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

    Kudos to @O2 for customer service today. Recommend going via app ‘Start a Conversation’ section.

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

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

  • 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).

  • 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

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

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

  • Kezzadosurf Kerwal (@Kezzadosurf) reported

    @O2 @Apple appauling customer service at the Nottingham O2 shop. Just needed to buy a replacement iPhone phone for my very ill mum!! Tried to overcharge me in order to change my contract! Would like to discuss this further! Thank goodness @johnlewishelp was next door. V helpful!

  • PhilLearney Phil Learney (@PhilLearney) reported from Bromley, England

    @O2 I can now see why you wanted to take this private, spent £2k plus with you at midday, three hours later a customer service representative is verbally laughing at us over the phone because the sims haven’t transferred. 🙄

  • LJ19714 LJ1971 (@LJ19714) reported

    @O2 recently delivered reconditioned iPhone X voice calls poor quality. People on other end of line says my voice fades in and out or like under water. Calling from my house. No similar problem with old iPhone (5s). How do I seek help. Can’t call you because you won’t hear me!

  • HildaOgdenOnSea Hilda Ogden (@HildaOgdenOnSea) reported

    @O2 I’ve raised it repeatedly throughout the four mistaken days I’ve been with you. I’ve spent more time chatting to your dire customer service than my own family, friends, and pets. In fact, I’ve just finished a 40 minute call. Not even my first of the day.

  • eurorich eurorich (@eurorich) reported

    @O2 I’m trying to cancel my contract. Your customer services don’t answer (one of the reasons I want to cancel). Can you help please?

  • OliverRoper_ Oliver Roper (@OliverRoper_) reported

    @O2 had poor signal for over 3 months with O2 @EE was never an issue. Person via DM has told me the network in my area is “busy” and I’ve been “unlucky” with this. No help. #o2 #1starcustomerservice

  • davidwright33 David Wright (@davidwright33) reported

    O2 need improve their customer services!! Told to wait 20 mins, came back, told another 20 mins but was then messaged 2hrs later!! I know you were busy but that's taking the mickey! @O2

  • pink_sunshine89 Lucy Williams (@pink_sunshine89) reported

    @O2 no signal in my area for most of this year, phone mast down for months.. try and talk to someone & get cut off… don’t even allow their LOYAL customers to complain @financialombuds should know about this!!

  • JamieBGall Dr Jamie Gallagher (@JamieBGall) reported

    @O2 I'm trying to swap my sim, it asks me to sign in to my O2 but the page fails to load. Any help much appreciated.
