    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • 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.

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

    @O2 I need help ASAP please

  • 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

  • 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

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Ealing, England

    @O2 The problem is the phone tries to switch to 5G where there is no coverage here so it results in no signal. That happens everywhere not just W5

  • 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

  • Paula_Griffin65 Paula Griffin 🏳️‍⚧️ 💙💖🤍💖💙 (@Paula_Griffin65) reported from Camden Town, England

    @O2 Hi, currently log into 02 Wi-Fi in places like Costa etc but need to change my details as the name it flashes up is incorrect. However it won’t accept either my email or my phone number to change details.. Help 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

  • jonathonfp Jonny Pugsley (@jonathonfp) reported from Camden Town, England

    @VodafoneUK I’m having a terrible time with @O2 right now. Mobile data where I live is so unreliable… I’m thinking of moving to you guys, but would love to try your network out first. Is this a possibility…?

  • 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 👏.

  • 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

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

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

  • 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

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • 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.

  • 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

  • jonathonfp Jonny Pugsley (@jonathonfp) reported from Camden Town, England

    @O2 your 4G service in London is absolutely dire currently. And you’ve just put my price up for the privilege of it.

  • NorthernlyExpo Andy Denial 📸 (@NorthernlyExpo) reported from Islington, England

    @O2 Just trying your Priority code in McDonalds but it’s not working. Just says it’s been used already.

  • 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.

    Hello @O2 Account no. 1044244169 Why has your colleague locked my android phone from using o2 sim that I've been using all along for number ending 702 ????? I done a sim swap in store today, still doesn't work on my phone, but other sim works. My mobile always been unlocked

  • goblinshagger Pheel-it Steak (@goblinshagger) reported

    So @O2 didn’t deliver my phone despite me paying for next day delivery, said phone wont be here tomorrow either or monday. Takes 2 days to do a credit check for a customer of 14 years apparently but 14 days to refund me my money too. Absolute joke of a company

  • fowell103 David Miller (@fowell103) reported

    @O2 how hard should it be in this day and age to get a signal on my iPhone in my garden let alone my house especially when your signal checker says the signal strength is excellent? Coverage is getting worse not better, do I have to change network?? #annoyed

  • charbarley Charlie Chenson (@charbarley) reported

    Why when you go to a large event like a concert or a festival does your phone never work? Like… what am I paying my bill for @O2 ?

  • liifeofzo Zoe 🍁 (@liifeofzo) reported

    @O2 Not yet, assuming I need to wait 24 hours until it can be sorted if it’s still not working?

  • TheBossnME Mark 🇺🇦 (@TheBossnME) reported

    @O2 Hello Yes, the message I received threw me too! It was through the messaging service within the app. the other day. I can forward it on, however what's the most secure way to do this?

  • justemmathatsit Emma (@justemmathatsit) reported

    If someone at @O2 would like to contact me about the appalling customer service we are receiving this morning, I’d be grateful. 2 hours, 5 people and no callback isn’t a great advert.

  • goblinshagger Pheel-it Steak (@goblinshagger) reported

    @RKnowles_Photo @O2 They gave me 35 quid credit but still haven’t done anything to fix it, got to the ombudsman and you’ll get a minimum of 75 quid compensation

  • BajiNahid Baji Nahid (@BajiNahid) reported

    @O2 Hey we are not able to avail the inclusive travel zone in New Zealand for some reason, it keeps saying we have no internet but yet the 4G sign is showing. We can call and text but cant use the data. Would appreciate any help.
