    @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

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

    @O2 I need help ASAP please

  • 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

  • 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

    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 👏.

  • 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

  • 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?

  • 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

  • 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

  • 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

  • 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.

  • 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

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

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

    @O2 hi, I told o2 that I was cancelling my contract and it’s not been done. I can’t get hold of the appropriate team too. Can you help please?

  • playpet1 playpet (@playpet1) reported

    @laine482012 @virginmedia @O2 What is wrong! Virgin over sell their service to get new customers, have you recorded things only to find part of the show missing? Slow internet ? This is because of where analogue is converted to digital their hubs are over loaded! Their network has too many people using it

  • DawnStanleyinfo Dawn Stanley (@DawnStanleyinfo) reported

    @O2 I’ve been with O2 for more than 15 years. Never missed a payment and yet my iPhone 11 (worst phone ever btw) costs me over £50 pcm. Are there rewards for loyalty? Can I trade in my 11 for this? #newdealsforexistingcustomers #O2

  • daanoctober e’lir daan (@daanoctober) reported

    @O2 is so so bad. 0/10 wouldn't recommend

  • SarahR_PR Sarah Regan (@SarahR_PR) reported

    Right @O2 this will be the fourth time of asking, can someone finally sort out my billing date?! I was promised it would be sorted this month and yet again nothing has been done. This isn’t good service at all!

  • CJSR1992 chris roberts (@CJSR1992) reported

    @tdavies2197 @O2 It's out of stock and they aren't delivering or you still have to wait and they didn't cancel the order?

  • muppetkeeper Paul (@muppetkeeper) reported

    @SabrinaBranwood @O2 @virginmedia Now phone up Virgin and tell them you have a problem, or want to reduce your speeds, or anything… Literally the worst customer service in the world.

  • BohnJeremy Jeremy Bohn (@BohnJeremy) reported

    @O2 finding it impossible to find out from web/app or phone how to cancel my disney+ and monthly insurance which I no longer need - please help!!!

  • Linkzy_x Jay (@Linkzy_x) reported

    @Aaron_Kasten Also upgraded from a Pixel 3 XL, call quality has been way superior in the UK on @O2. No fingerprint issues at all, but I know what you mean about the slippery glass, I've woken up to find mine's landed on the floor each morning so far... Waiting on a case for this bad boy.
