    @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 🙄

  • 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).

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

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

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

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

  • 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.

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

  • 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

  • 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👿

  • 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 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!

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

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

  • 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.

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

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

  • 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.

  • 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

  • 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?

  • 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!!

  • 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.

  • 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

    @O2 @EleanorGrace09 I'm the same and sadly we've lost signal on old sim,my dad's old number which he wants to switch now says it's not been recognized when trying to call it 😒😒😔😔

  • chloe_slipknot Chloe Vincent ☾ (@chloe_slipknot) reported

    @mairead_p @O2 Yeah it’s defo bad at the moment but now I’ve switched to 4G instead of 5G it’s fixed my data issue, calls can still be a bit iffy though!

  • Epic_Kirsty Kiki (@Epic_Kirsty) reported

    @thepmadden @O2 I've been having almost the same problem...I lost the SIM card, so now even though I have the email and password for the account I am unable to cancel my contract. In March I've spent over 9 hours trying to get through on the phone and my official complaint email is ignored.

  • NinaMoo00916966 Nina Moore (@NinaMoo00916966) reported

    @O2 still awaiting a manager call back as promised 48 hours ago .. being a loyal customer gets you nowhere!!

  • Epic_Kirsty Kiki (@Epic_Kirsty) reported

    @O2 Hi, I sent a complaint email to O2 on 03/03/2023. Seven working days have now passed and I am still awaiting a response. I made clear in my email my intention to cancel the account and I feel like O2 are dragging their heels on purpose to try extort more money from me.

  • Ennelle E****E (@Ennelle) reported

    @O2 Do u have an email address I can contact u on with my details as having issues with direct messages not being sent to you. Thanks.

  • Samanth73659619 Samantha sanderson (@Samanth73659619) reported

    @virginmedia Hello, o2 won't let me cancel without paying a fee. You have reduced the costs of my tv package which has been very helpful, but @O2 are refusing to do any offers and want to charge me to leave.

  • lestereverton80 ᵀᴼᶠᶠᴱᴱᴹᴬᴺᴸᴱˢᵀᴱᴿ✨1878 (@lestereverton80) reported

    @O2 can ya help me please

  • nikinak84 Nicola Piggott (nee Richardson) (@nikinak84) reported

    @O2 He lost signal this morning, I'm at work so keep trying his old number which says not recognized. They have got the new sim card in a phone so I will know when it's transferred. Hopefully it'll be done by then. Thanks for getting back to me

  • Epic_Kirsty Kiki (@Epic_Kirsty) reported

    @O2 @AdamWil44010035 Honestly Adam, it's 2023 and O2 out here acting and behaving like it's 2003. Make sure you write an official complaint so they can leave you hanging for 2+ weeks (and counting). I'd like to recommend literally anyone except O2. Stop supporting these incompetent clowns bro.
