  • 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

  • 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 👏.

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 simply dreadful customer experience tonight -felt really let down

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • juliet_gough juliet gough (@juliet_gough) reported from Stevenage District, England

    @O2 I have an enquiry and can’t find an answer on the ‘My O2’ page. Please help. #CustomerService #o2

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • 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

  • Mattoco Matt O'Connor (@Mattoco) reported from St Albans, England

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • 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

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • 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

  • 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

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • 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. 👌👌👌

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • 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

  • a700c1521f4d43f Carol Johns (@a700c1521f4d43f) reported

    @O2 what's going on with O2? My signal has been rubbish for a couple of weeks now. Did what you suggested, not working. Your website says a local mast removed, will update on 28th May. #stillnoupdates

  • DQStuff David Quainton (@DQStuff) reported

    @benwood @virginmedia @O2 Everyvirg O2where Can’t fail.

  • 1997whovian Lauren Brown 🐧 (@1997whovian) reported

    @O2 It's been about a month now and you've still not fixed the data speeds in my area. Ever since you began improving the network it's been slow! How long does to take to fix a mast? Not this long surely. Absolutely ridiculous

  • tmarshdesign Tom Marsh (@tmarshdesign) reported

    @O2 hi I’ve got an issue with my Apple Watch series 6 which is on contract and bough from you, would I need to talk to apple about it or you guys?

  • asteelbath Alastair Steel (@asteelbath) reported

    @O2 I've spoken to 202 twice this month and they've given me all the usual guff. Apparently you are upgrading! Presumably degrading the service first so that the 'upgrade' seems better. If you can't keep the basic service working, tell people in advance.

  • forest_jay Jay (@forest_jay) reported

    @halftimepies @CarlosNFFC @O2 I've had a 5g SIM for 6 months. Never seen it go on to 5g ever

  • dilligaf2k10 BearWith 🐻 (@dilligaf2k10) reported

    @o2 why is your connection on 4G so crap in Brighton & Hove?

  • richstone59 Richard Stone (@richstone59) reported

    @O2 Are you having 4G issues today. Phone is fine on WiFi but 4G not worked for the last couple of hours (Manchester)

  • connorsayers18 DoctorWho SF (@connorsayers18) reported

    @O2 The status as changed. There is a mast in the area not working and being investigated so it explains my slow 5mpb data

  • Jemah1983 Jema Hart (@Jemah1983) reported

    @O2 Yes the guy on the phone said he set it all up. I can text and call him and him me but 4g is still not working.
