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

  • JoshBates Josh (@JoshBates) reported from Paddington, England

    @O2 I got this sorted doing this however this is really poor service. This should be an easy, self-service digital journey. Absolute joke that this took 35 mins for both me and your staff. Total waste of time. Please feed back.

  • 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.

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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.

  • 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

  • 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 👏.

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

    @O2 I need help ASAP please

  • 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?

  • 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

  • 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

  • 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

  • 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.

  • 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. 👌👌👌

  • 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!

  • 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

  • MinniMilo MiniMilo (@MinniMilo) reported

    @O2 thats what being on O2 feels like, your 4g coverage is awful

  • MoneyTips19 Gaz (@MoneyTips19) reported

    @O2 Hi, is the voicemail down, as everytime I call it cuts out instantly

  • phorenzik Stu (@phorenzik) reported

    @commsanddata @O2 I've quickly realised that. I'll probably just get the bank to cancel the direct debit. It shouldn't be this hard to cancel. I'll never go with them again.

  • RobJLow Robert Low (@RobJLow) reported

    @O2 Currently very frustrated: I'm trying to get a refund on my final bill, and having very little joy by trying to call customer services. After fifteen minutes, I was told I would be put through to the department who could do it, then the line dropped. Who can I call?

  • SuprBrwniLatte MH (@SuprBrwniLatte) reported

    @O2 I want to cancel my contract because the service is shocking. I was promised 5G I’m just about getting 3G. What’s the point of me paying monthly for something I’m now getting.

  • em_doapsi Diary of a Painfully Shy Introvert Blog (@em_doapsi) reported from Hinckley, England

    @O2 and giffgaff sort your network out! We can’t use it in Hinckley it won’t work at all! @giffgaff

  • WarrenSpeed1 Warren Speed (@WarrenSpeed1) reported

    @O2 #TBT when your signal and data were a lot better than the crap it is now. You have even confirmed that their are major issues with the masts in my city which are hugely impacting our services. STILL waiting for your retention team to call me regarding leaving my contract.

  • varivarivari vari (@varivarivari) reported

    @O2 The link won't even load is how bad your network is right now 🤠

  • WayneyoWayne wayne Tavit (@WayneyoWayne) reported

    @O2 The wife has the same issue. Different handset, different sim, same network.
