    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

  • 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

  • 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.

  • 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 👏.

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • 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

  • 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

  • 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

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

  • 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

  • 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

  • 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!

  • 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

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • join4te Jay (@join4te) reported

    @O2 Day 89 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.

  • naughto_mc JaniceMcN24 (@naughto_mc) reported

    @virginmedia @TheBHF @O2 Signed up for tv, broadband and phone with services starting on the 26th January. Having called several times, spent hours on WhatsApp , an IT problem raised on 1st February, with a response within 3 to 5 days, I am no further forward. Customer service is shocking #notimpressed

  • Anqi_Win Anqi Win (@Anqi_Win) reported

    @O2 is there anybody out there?? @O2 if I could I would cancel contract! Worst service ever!! #youcannitmaiethisup 10 days and counting to get voicemail set up. Rediculous😡😡

  • jjmib jemma (@jjmib) reported

    Only been with O2 for about 6 weeks and the signal is SHOCKING even when it says I have 4g nothing will load. In main towns and cities too! Will they let me cancel?? @O2

  • chupchupchee Kathleen Manzo🍀🍀 (@chupchupchee) reported

    @saraduff @O2 I’ll advise you quickly look out for @DarcyDrollinger for help.

  • bigman_andrew Andrew Oldham (@bigman_andrew) reported

    @O2 I'm an existing customer wanting to buy a new sim...why has it taken me 2 hours of being on live chat and I'm no closer!!! Avoid O2 people...awful service...what a waste of life

  • simonhouston68 Simon Houston (@simonhouston68) reported

    @O2 So I’m now effectively being trolled by the @O2 customer service team. Having been left out £800 out of pocket after what they concede was their mistake. Beyond belief. Massive mistake to leave @VodafoneUK

  • c20023 Chris J T 🏃🏻‍♂️🇬🇧🏃🏻‍♂️ (@c20023) reported

    @O2 I like how o2s # is #betterconnected yet I’ve had extremely poor signal for the past two weeks

  • simonhouston68 Simon Houston (@simonhouston68) reported

    @colinmccredie @O2 We were talking to their online help team. When they realised it was their mistake, they have stopped replying.

  • martin_youldon Martin Youldon (@martin_youldon) reported from Southend-on-Sea, England

    @O2 been trying to get through to customer services for the past two days & after 15 mins in the queue gave up,
