  • 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!!

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

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

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

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

  • 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

    @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

  • 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).

  • 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!

  • 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.

  • Jay_McB Jason Brown (@Jay_McB) reported from Newtownabbey, Northern Ireland

    @virginmedia come on I have 4 Sims with VM. Even put something together online. Will @virgin customers be getting any rewards or paybacks like @O2 had to do when they kept getting network problems 😜

  • 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.

  • 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.

  • 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 =)

  • 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.

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

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

  • 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

  • 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?

  • 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.

  • 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 🙄

  • StephenScarth Stephen Scarth (@StephenScarth) reported from Bangor, Northern Ireland

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

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

    @AdamYoungMedia @O2 I had similar issues and I contacted @jay_hack22 on Instagram and WhatsApp +1 (720) 805‑6127 he helped me and he’s reliable

  • Sarac2404 Sara (@Sarac2404) reported

    why is there poor network in Llandudno. There is no signal on the high street for Internet and often cant make a call. I stay loyal to O2 but will have to think of looking elsewhere its not rural it is a busy seaside resort and I am sure I am not the first to complain @o2 #o2

  • Ob65Tom Tommy #💜 #💙NHS #FBPE #FBPPR (@Ob65Tom) reported

    @EleanorRylance @O2 It's the choice of the network. I'm currently with Tesco mobile, who've told me, I will still be able to use my phone nothing has changed, that I won't be changed. I have a trip planned in the next few weeks. If I'm charged I'm going back to 3, who definitely don't.

  • m66rus Mark Russell (@m66rus) reported

    @o2 your current service coverage is 3rd world what is going on or is it time to move all of my contracts elsewhere !!

  • SgawShaw Muriel Sgaw (@SgawShaw) reported from Seaham, England

    @O2 @EleanorRylance And sack the poor employee?

  • EcolanderUK Ecolander UK (@EcolanderUK) reported

    @Sarac2404 @O2 Very true! The network is awful around there and also on o2. Go in to M&S and it is a black hole

  • SMackrell Mrs Mac (@SMackrell) reported

    @O2 Hi, I have been trying to sort out a problem activating Disney+ (6 month free offer) with online chat for 2 hours now, still no activation email received. Please can someone help? Disney+ have advised that I need an activation email sent manually?

  • 1990_cia Ciaran (@1990_cia) reported

    @O2 my signal has been rubbish for weeks, just got through to customer service and my call dropped again. I'm paying £26 a month for this rubbish. Not acceptable!!

  • darrenjadams Darren Adams (@darrenjadams) reported

    @disneyplus @O2 - can you sort out between yourselves who deals with issues with the 6 free months offer? Spoken to agents from both companies this evening and both have said I need to contact the other... and neither have been able to activate the offer. 90 minutes wasted.

  • coleman_wendy Wendy Coleman (@coleman_wendy) reported
