    @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

  • 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

  • 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

  • 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.

  • 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

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

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

  • 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 St Albans, England

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

  • 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

  • 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

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

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

  • 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. 👌👌👌

  • 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 👏.

  • 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

  • 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

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

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • 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.

  • 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

  • bradders2010 Bradley (@bradders2010) reported

    @O2 @SkyHelpTeam how do I report a blackout area? Intermittent connection where I work and not just me having the issue people on o2,sky and Tesco all having slow/dropping out connection despite having 3 bars.

  • emmajg 🌸 Emma 🌈 (@emmajg) reported

    @bt_uk Once I can contact my parents I get the info, I have to wait for them to get to an area with mobile signal & they call me. It's crazy it's only in South Wales near Chepstow yet no @O2 or any mobile company has signal so can't even call 999.

  • xLucyfx xLucyfx (@xLucyfx) reported

    @O2 Hi, I'm not longer a customer with you but I've recently had an email to say you owe me a refund and to provide you with my details. Is this safe and genuine please?

  • sternejohn John Sterne (@sternejohn) reported

    @O2 In my house at all times, it’s so bad that I’ve resorted to calling most people on WhatsApp. Trouble is whenever I get calls from anyone on landlines they can never hear me.

  • martynbroad Martin Broad (@martynbroad) reported

    @O2 @JessIsCuty Same here in Swansea, full signal yet no or poor service

  • HaloScotgal Sharon Wilkinson-G (@HaloScotgal) reported

    @JimmyCardiff @O2 I had the same trouble - if you choose the forgot password option it will let you set one. Pretty poor that never sent the email address and password info in the first place though…

  • matthewjorange ᗰᗩTT-ᕼEᗯ ᗰᗩKᗩᐯEᒪI (@matthewjorange) reported

    @O2 you have got to be the worst provider in the UK. NEVER ANY SINGLE. sort it out please.

  • palfreyman1414 Ravi Nair #FBPE #PerfectPorkPie #JohnsonOut#FBPPR (@palfreyman1414) reported

    @FelicityCloake @O2 ****.

  • palfreyman1414 Ravi Nair #FBPE #PerfectPorkPie #JohnsonOut#FBPPR (@palfreyman1414) reported

    @FelicityCloake @O2 I worked at a call centre once where a particularly slack staff member put a customer on hold, went out and smoked a leisurely joint, came back and took him off hold, and said: "I hope you enjoyed the music, sir."

  • andrewjminter Andrew Minter (@andrewjminter) reported

    @O2 I’ve had no signal on my phone for a week now; you said a mast wasn’t working (200m from our house), but would be by 20 May. Now it won’t be until 27 May. That’s 2 weeks without signal…do I get a refund and WHEN will the mast be mended??
