  • 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

  • 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

  • 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

  • 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

  • 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 👏.

  • MANLIKENAIJA NAIJA BOI (@MANLIKENAIJA) reported from London Colney, England

    £105.03 A MONTH AND FOR THE LAST 6 MONTHS NO NETWORK !!! @O2 DO BETTER

  • 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

  • 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

  • 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. 👌👌👌

  • 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

  • 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

  • peterives50 Peter Ives (@peterives50) reported from Enfield Lock, England

    @O2 Happy Monday to everyone but O2 who still can't sort out my text and calls problems after at least a month 😡

  • MANLIKENAIJA NAIJA BOI (@MANLIKENAIJA) reported from London Colney, England

    @O2 worst bloody network on the planet 6 FREAKING MONTHS I HAVE NOT BEEN ABLE TO USE MY PHONELINE DIE TO A MAST PROBLEM AND I AM STILL FORCED TO PAY FOR IT AND THEN HAVE TO PAY FOR ANOTHER NETWORK SIM JUST TO STAY AFLOAT KMT NEVER AGAIN

  • 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

  • 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.

  • andy_boniface Andy Boniface (@andy_boniface) reported

    .@o2 I am not an O2 customer but you keep sending me bills! I am on hold for 30+ minutes to your useless organisation to fix your stupidity.

  • STORMTIGER5 Tracy Hanson (@STORMTIGER5) reported

    @O2 It's incredibly rude to ignore people, even more rude to run a comp where 4 days before you tell people they can't have their prize, offer another one, and then mess the same person about over that!!!!!

  • TaneJWils Tane (@TaneJWils) reported

    @O2 what the hell has happened to your customer service!!!!!!!!! Been trying to call to add a spend cap as can’t seem to do it via app!! Holding all morning and cut off 3 times

  • DJ_Mixmeister 🎈Nigel (50s Club) (@DJ_Mixmeister) reported

    @virginmedia @O2 2 days now and counting, Virgin are you actually doing anything to fix this or are you sat on your lazy arses just drinking tea & biscuits all day?

  • ClaireCarroll26 Claire (@ClaireCarroll26) reported

  • eliasgraham94 **** the halls 🎄(he/him) (@eliasgraham94) reported

    @O2 No unfortunately not. I imagine it’s from the storm thing that went on yesterday and through the night. I just thought it would be back by now as it’s calmed down weather-wise

  • chucklebus1 chucklebus (@chucklebus1) reported

    @O2 location services are not working on my kids phones since I asked for the age restrictions to be put on to prevent access to explicit material. I’ve put on hold for 15 minutes then transferred and cut off

  • matyd88 Mathew David (@matyd88) reported

    @O2 you escalated my issue. To call me back. I asked you to leave me a number as I have no signal! To just receive a text that sends me to a unhelpful link! Terrible customer service
