  • 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

  • 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

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • 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

  • 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

  • paul_a_lewis Paul Lewis (@paul_a_lewis) reported from Barnet, England

    @O2 my wife joined O2 today and ordered a new phone however she provided you with the wrong email address, can you help change it? Thnx

  • 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

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP please

  • 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. 👌👌👌

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Any plans on enabling sms over wifi calling? I used to be with @EE and I could call and sms with wifi calling but seems your network only supports calls?

  • 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 👏.

  • 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

  • CCTVinCare 💜💚Care Campaign For The Vulnerable💚💜 (@CCTVinCare) reported from Gerrards Cross, England

    @O2 amazing customer service experience on your 202 called MARCO. 🙏

  • 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

  • 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

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • 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

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • clintskeeey Clint (@clintskeeey) reported

    @Jesssoulsby02 @O2 Hi Jess. No they were awful. Said they would give me something like £20 as a goodwill gesture. I left them

  • andy_uk44 I am just me (@andy_uk44) reported

    @O2 only 6 more days to get the signal issue sorted and seeing nothing has been done since last week then I will be cancelling my contract soon enough and then I will have no means of phone contact for incoming calls for jobs

  • daneMjohnson Dane Johnson (@daneMjohnson) reported

    @O2 Seemingly whilst im at home. Only just noticed it happening but i think its happened a few times over last couple of weeks. My phobe randomly pings to say i have a voicemail which turns out to be brand new....only my phone never actually rings in the first place

  • madcow42 Sarah 🌼 & Jasper 🐾 (@madcow42) reported

    @O2 I have, but I also have an O2 sim which I’m having the same nonexistent network issues. Apparently it’s all across the Wirral, masts being down

  • rbarkley82 Robert Barkley (@rbarkley82) reported

    extremely disappointed in @O2 yet again... I upgraded online and paid for delivery before 12noon today... Phoned DPD who said they dont do a pre-12 delivery service... so what did I pay £5.99 for? and to top it all off, its not getting delivered until Monday!

  • el_lad67 BriBhoy (@el_lad67) reported

    @NameOfTheMaster @O2 After numerous messages on here, trips into store and phone calls to O2 they’ve told me there’s been an issue with the warehouse (even though my handset shows as dispatched and delivery completed) The only way to rectify this has been to cancel the order ……..

  • MarinaMacTavish Marina MacTavish (@MarinaMacTavish) reported

    @O2 is there a problem with signal coverage. I'm expecting a call from my drs and no network whatsoever!

  • AndiLyth 🌻Andi Lyth🌻🇹🇷 (@AndiLyth) reported

    @O2 what’s going on with your service?

  • mckennajames227 James McKenna (@mckennajames227) reported

    @O2 TS25 5TG and TS27 3LB. Still no phone signal.

  • ohemgem_ gem 🌸 (@ohemgem_) reported

    Anybody else on .@o2 and been struggling to get a decent signal for weeks now?? Lucky if I even get 4G these days! 1 bar on 3G. And this is what I pay a hefty contract for? Ridiculous.
