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

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

  • Deadandgone70 Joel Ferguson (@Deadandgone70) reported from Newtownards, Northern Ireland

    Glad I’m leaving @O2. Trying to recycle my phone and according to CEX, TescoMobile and Game the small mark on my phone wouldn’t be a problem. But send my phone off and they say they’d give 50% of the value. Jokers like. Even in store they said it wouldn’t be a problem

  • 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

  • DAVIDBUZZ2904 DAVIDBUZZ2904 (@DAVIDBUZZ2904) reported from Lisburn, Northern Ireland

    @TalkTalk No the @TalkTalk number was 03451720088 And @O2 give me 03451720091 The email number was 03451720032 No success at all very bad customer service so far !!!

  • 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 🙄

  • 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!!

  • 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 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.

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

  • SWAshleigh Ashleigh Shaw (@SWAshleigh) reported from Ballygowan, Northern Ireland

    How do I make a complaint with @O2

  • 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?

  • 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 😜

  • furious_liv whatmakesmefurious (@furious_liv) reported

    @O2 charged me, despite cancelling contract in the 14day cooling-off period. Sim not even used. Called to get a refund. Terrible customer service. Now only been partially refunded. Absolute crooks.

  • chels_louox chels (@chels_louox) reported

  • hannworkman_ Hannah 🌸 (@hannworkman_) reported

    @O2 @tescomobile i have no signal but the website says i should have signal here so what can i do? I have turned my phone off and back on and still isn’t working.

  • mwal86 Maciej°W (@mwal86) reported

    @O2 Haha 1. New contract with o2 its better than renewal 2. Network Signal its terrible 3. And Prices are stupid! Been with o2 nearly 14 years and I can say that honestly

  • Becky_141 Becca (@Becky_141) reported

    @O2 hi there if I upgrade to get the galaxy fold 3 I will pay 4p more over 36 months than if I was to pay £50 upfront and start up a brand new contract. But where is the incentive to actually stay with you guys if I was to just start up a new contract with you? Help please!

  • wilcochris Chris Wilcox (@wilcochris) reported

    @O2 The big question is: are you going to be like the others that look after their customers and reintroduce roaming charges. You’ve already dropped down your AU allowances when you said you wouldn’t

  • sabbymakaveli Sabby (@sabbymakaveli) reported

    @o2businessuk @O2 Don’t ever use o2 business!! They sign you up through 3rd parties and then absolve all responsibility. Been waiting 4 months to get my query resolved and they just send you round in circles! My Business has lost money due to their shocking service!

  • mike_mellish Mikey.M (@mike_mellish) reported

    @O2 As an existing customer I was just wondering how do I get one of your fab surprise boxes I’ve also just taken out an extra contract with yourselves too

  • ddd1820 Cam (@ddd1820) reported

    @O2 Absolutely poor service in the Kilburn store. Told me to “go to EE then’. The assistant was not willing to help. So annoyed.
