  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • torgo Daniel Appelquist (@torgo) reported from London Colney, England

    Do you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

  • Mattoco Matt O'Connor (@Mattoco) reported from St Albans, England

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

    @VOXI_UK I have been on a staycation this week I am appalled at how poor your reception is in many parts of South East. Going back to @O2 as sim only!! Very frustrating 😕 missed many important phone calls. Pm me to discuss

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 simply dreadful customer experience tonight -felt really let down

  • Atanvarne ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England

    @O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from London Colney, England

    @O2 full 4G signal in Chelsea and can’t even load a PDF attachment or Instagram post. Absolute shambles. Same over in white city. Same in London Bridge. Got better service last week 2000M up a mountain in Austria

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    2/2 @O2 promise to call you back, but as yet nothing, they promise to escalate to a manager, but surprise they don’t call you back either, their Twitter also ignores your serious concerns.Think seriously before choosing @o2 if there’s an issue THEY don’t seem to care! @VMO2News

  • lordshaun_ Lord Shaun O’Brien 🇺🇦 (@lordshaun_) reported from London Colney, England

    The customer service of @O2 is truly one of the worst I’ve ever come across. They tell me to call, but I can’t because they’ve cut off my phone. The number goes through to a bot. Quelle surprise! I paid the bill, as always, and yet here we are. Been on the chat thing for four hrs

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    1/2 BEWARE everyone considering switching to @O2 They offer to port your existing number from your previous provider, which is really important to many, but FAIL miserably, when you call customer services multiple times, they promise a 4 hour resolution, this never happens..cont

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • JulesyJulie julie stokes (@JulesyJulie) reported

    @O2 why is no one taking calls? Been phoning all day!! Poor poor service!

  • DamnedMenace DamnedMenace (@DamnedMenace) reported

    @O2 I have searched your website for known faults with the @oppo phones but can't find anything relating to being cut off mid call when I have full signal. Tried the "fix my fault" option too and got nothing. Help

  • AllanT1978 Allan T (@AllanT1978) reported

    @O2 @Apple Don’t switch to o2! Worst network by a mile. If you want to lose signal and data every single day, then go ahead. Had enough and switched networks and already noticed a much better signal and no loss! Lost £1000’s in business due to o2 and would only recommend customers leave

  • helen_ramshaw Helen Ramshaw (@helen_ramshaw) reported

    @O2 you are the worst company ever! Moved to you as a customer 3 weeks ago and the signal is so bad I can’t make a functional call. Tied chat, divert you to website. Website diverts you to chat and round you go in a circle. No one answers the phone. Absolute disgrace

  • F1_Chef Chef One (@F1_Chef) reported

    @O2 hey, can you guys check something for me please? I’m in the UK so I can’t call Customer Services. Added a bolt on today to my account but it’s not appearing to work, I just wondered if someone could check it’s active and added ok, please?

  • kaeblackett Kirsty Blackett (@kaeblackett) reported

    @O2 what is going on with your signal??? It’s terrible last 3 months up and down the uk! Drops out at home completely it used to be good. Everyone I have asked is saying the same thing! Over 20yrs I have had my contract and I’m seriously considering swooping

  • xxkaterachelxx Katelicious (@xxkaterachelxx) reported

    @O2 WHY am I still waiting to hear from your fraud team from 31/08/21 after calling and being told I’ve been made a priority?? You’ve taken over £100 from me and don’t seem to be willing to rectify this problem!!!!

  • Robdavies1 Rob Davies (@Robdavies1) reported

    @O2 For the avoidance of doubt, this has been happening since my handset upgrade, (roughly 18 months). I'm familiar with your default replies and guarantees of network upgrades. You've promised this for a while now. Like I said, actions speak louder than default scripted responses.

  • PotnoodIefringe 🌚 (@PotnoodIefringe) reported

    And don’t you dare “We're sorry to hear this” me your service is shite @O2

  • Krys_Champlain Phoenix (@Krys_Champlain) reported

    @O2 quick at taking your money from you but make it hard for you to contact them when you’re having issues with a device.
