  • 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.

  • 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

  • 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?

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • 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. 👌👌👌

  • 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

  • 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

  • monicathenurse Monica, BSN, RN, MFCI (@monicathenurse) reported from Walthamstow, England

    @O2 hi I called customer service but they can't find my account I want to give notice to cancel my contract.

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported from Walthamstow, England

    @O2 I don’t know what I’m paying for? Unless I’m somewhere with WiFi I have the worst internet, anywhere I go! I’ve tried all the steps to fix and still terrible internet. Unacceptable!

  • 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

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

  • 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

Latest outage, problems and issue reports in social media:

  • McGregor_graeme Graeme Mcgregor (@McGregor_graeme) reported

    @O2 That doesn't answer my question as to why it's been like this for at least 4 months yet you continue to charge me for a service you aren't providing and now want to charge me 13% more for not providing that service

  • McGregor_graeme Graeme Mcgregor (@McGregor_graeme) reported

    @O2 can you please tell me why, since at least November last year, there has been no mobile data signal in #cupar #ky15

  • PilgrimChris PilgrimChris (@PilgrimChris) reported

    @alohamora____ @iamawty @O2 We do. We can choose not to use their service.

  • DrCox222 DrCox222 (@DrCox222) reported

    @O2 customer service they can’t help customers with the greedy price increases tut tut

  • alohamora____ al🐱🌅 (@alohamora____) reported

    @PilgrimChris @iamawty @O2 Yeah but our prices won't come back down when Inflation does will it?

  • deLaceyMusic de Lacey (@deLaceyMusic) reported

    @O2 How does "I live internationally, please can I cancel a different way" take over 24 hours to get a reply, which suggests "call us on a +44 number"???

  • Chris61172903 Chris Haywood (@Chris61172903) reported

    @JacCooper1 @EnglandRugby @O2 True; we never really got clarity on how many additional changes he was permitted to make, if at all.

  • red_ed_A red red rev (@red_ed_A) reported

    @Gavlar321 @EnglandRugby @O2 Watson provides near world-class cover at 15 which Arundell can't yet. I've always thought he's better suited at 15 than wing. He was outstanding in the 2017 Lions. The lack of centre cover is a good point. It essentially means Farrell will never be subbed for Smith which is sad

  • ellielouise_88 𝙴𝚕𝚕𝚒𝚎 𝙶𝚘𝚕𝚍𝚜𝚖𝚒𝚝𝚑 (@ellielouise_88) reported

    @O2 Customers SHOULD be able to cancel when you are putting the CONTRACT up by 13.4%. Why do we have to keep our end of the contract, but you don’t have to?

  • Shelleytracey Shelley Tracey (@Shelleytracey) reported

    @O2 you have let your customers down. Putting up your prices to incorporate a 13.4 pc inflation rate + another 2 pc is so unfair - especially as the rate of inflation is lower than 13.4pc now:(
