    @O2 Hi my gran is an elderly customer of 02 and keeps getting calls from 02 and has said many times not to ring her again and you keep doing so I want an explanation !

  • mcadam_rob Rob McAdam (@mcadam_rob) reported from Lurgan, Northern Ireland

    @coolfm just when you feel it could be you winning the cool cash call , the stupid networks @tescomobile & @O2 are down and have been for over an hour now 😠

  • 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).

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

  • niamharmagh11 Niamh Thornbury (@niamharmagh11) reported from Lurgan, Northern Ireland

    Is anyone else having problems with the 4g on @O2 😭 please tell me my phone not broke

  • 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

  • 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!!

  • leannereid1988 leane reid (@leannereid1988) reported from Castlereagh, Northern Ireland

    @O2 in o2 shop in newtownards the 3 fellas in the shop couldn't have bin any nicer and very helpful even when the problem was my own fault! Saved me a trip to Samsung! Def need a pay rise!! Thank you =)

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

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

  • 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.

  • 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.

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

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

  • 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

  • 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.

  • 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

  • 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!

  • 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👿

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

  • mikeebee27 Mike (@mikeebee27) reported

    @O2 Very slow data performance on 4G and website says it can get busy in this area. Really there are not many houses. Not good from 02

  • darrenwhitehall Darren Whitehall (@darrenwhitehall) reported

    Such a stressful day and @O2 can seem to answer any direct simple questions. This is so frustrating. I am so tired and angry by there customer service team

  • stringofears stringofears (@stringofears) reported

    @O2 I'm sorry, but there is no way I am providing you with my address and phone number over social media. Also, you're missing the point. "Looking into it" won't change the fact that you do not respect your customer marketing choices and you should be reported to @Ofcom .

  • TheGenghisKen Ken Smith (@TheGenghisKen) reported

    Hello @O2. Was helping a friend setup a phone for elderly person on PAYG contract. They accidentally mixed up "phonebook" with preinstalled "directory" contact on O2 SIM and got charged £1.50 for a 1 second call. Please help refund this outrageous cost, which was not their fault.

  • Lee_Smithh Smithy🏴󠁧󠁢󠁥󠁮󠁧󠁿 (@Lee_Smithh) reported

    @O2 can communicate sufficiently on here to customers about non vegan products but to people who pay their bills and have no service what do ever? Shocking. I’d like to speak someone please since this is the 103rd time of trying to contact you

  • TheGenghisKen Ken Smith (@TheGenghisKen) reported

    Hello @O2. Was helping a friend setup a phone for an elderly person on PAYG contract. They accidentally mixed up preinstalled "directory" number on O2 SIM with paid directory enquiries service and got charged £1.50 for a 1 second call. Please help refund this outrageous cost.

  • rubygrace212 Ruby Prior (@rubygrace212) reported

    @O2 hi o2. We have been trying to ring like asked from the o2 shop. However, it’s very keen NOT to help us in the slightest and hangs up after saying ‘bye.’ We just want to migrate a number a pay of an existing contact. Didn’t think it would be that difficult!

  • Brandon22376427 Betty Blue (@Brandon22376427) reported

    Absolutely shocking customer service from @O2 I’ve wasted five hours of my life on phone calls and chat and have got precisely nowhere. Anyone else?

  • skullmonkey7735 🇮🇪 Stiofán Ó Frighil F.C.D🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@skullmonkey7735) reported

    @markxdavies @O2 Nope, not a word until I contacted them.. Not an email, nothing.. Plus you're down the cost of a new handset!!🙄 All I got was a link on here, after I'd made them aware.. Then today, about 2, I'd a text telling me it'll be back in 48hrs! But it was obviously back as I got a text!
