  • 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.

  • 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

  • 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 🙄

  • 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.

  • 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!!

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

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

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

    How do I make a complaint with @O2

  • 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.

  • 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 😜

  • 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

  • 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?

  • Utter_Dil_Emma Mad Madame Em (@Utter_Dil_Emma) reported from Belfast, Northern Ireland

    I assume my bus home crashed and I died because hell is surely dealing with @O2 customer service chat for a ******* hour and a half.

  • 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

  • m0rven morven (@m0rven) reported

    @O2 - I need to reactivate my dad’s PAYG sim, can you help with that? (He doesn’t do technology, the sim used to be mine!)

  • v93704347 v (@v93704347) reported

    @O2 my monthly contract recently ended so I asked to switch to pay as I wanted to keep my current number You guys sent me a new sim with a new number I rang up to swap numbers and they told me it’s done but It isn’t as I cannot receive calls or text on my old sim no more help!

  • r_thurston Rupert Thurston (@r_thurston) reported

    @O2 thoroughly unimpressed with your o2 recycle service and now understand why you keep it at arms length. Had sent off my old handset. Now just noticed money taken back off my bill without communication or return of handset!

  • YuriBoy70984836 Yuri_Boyka (@YuriBoy70984836) reported

    @O2 I've recently joined o2 from three network taken out a 36 month contract Samsung note 20 ultra at around 61 a month no 5g in my area called up to be offered a measly£3 discount a month wish I went with sky or ee better perks better coverage cheaper.

  • Robot_Logic Robot Logic (@Robot_Logic) reported

    @O2 Basically you're banking on people getting the 'free' Disney + and then forgetting to cancel subscription. And you're just misleading people, when the last thing they need if choosing some 12-24 month contract, is the confusing mess you've deliberately engineered.

  • josieshmelon Josie (@josieshmelon) reported

    @O2 tried to add an Apple Watch to my contract and it gets to the review and then when I press submit says there’s an error and to call 202 but they can’t do anything? Is the website down?

  • deanprobert89 Dean Probert (@deanprobert89) reported

    @rhianlinecar @johnthejack @O2 That’s o2s biggest problem. Any town or city centre the signal is terrible not the south coast. Need more investment on their network. 4G is abysmal. As soon as my contract is up I’ll be jumping to Vodafone or EE.

  • Daggy332 Daggy33 (@Daggy332) reported

    @O2 I'm thinking of joing your network with one of your SIM only deals. But will it support esim. I have galaxy watch and its important this is supported with my phone

  • KellymarieSelb1 Kelly-marie Selby (@KellymarieSelb1) reported

    @O2 using you chat service and been waiting over an hour for a reply??? Really would like so assistance please

  • ChezPoule Deb (@ChezPoule) reported

    @O2 Trying to pay off my device and buy a new phone. Spent all day waiting for a call but nothing. Can't pay off online and the App never works on my device. Want to speak to a real person. Frustrated
