    @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

  • 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

  • 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.

  • 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?

  • 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!

  • 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

  • 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 👇

  • 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.

  • 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

  • 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

  • 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

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • 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

  • 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. 👌👌👌

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • 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

  • 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.

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

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

    @O2 Disney Plus Activation problems persist. Customer Services reloaded the extra but still have error code 404 page not found. Never received an email or text to activate extra. Have tried activating via the App and Web but nothing..

  • scoobyhugh8 Hugh Toner (@scoobyhugh8) reported

    @O2 need help with my sons upgrade as the new phone ain’t working on his new sim

  • domharding Dom Harding (@domharding) reported

    @O2 Two online forms submitted with PAC code, two visits to an O2 shop, lots of time sat in call queues before being cut off, and still no number transfer - please help!

  • WrightDpw David Wright (@WrightDpw) reported

    @kojecat @O2 O2 clearly underestimated the volume of customers who would take up the offer. I have spoken with their customer services on 2 occasions this week and have been told different things each time. This is a technical issue which should have been sorted.

  • PaulRolfe Paul Rolfe (@PaulRolfe) reported

    @O2 so… my mother has been scammed by you guys in to taking out a contract and she didn’t activate the sim and phoned to cancel the contract inside 24hrs but you are deducting monthly money. How the hell does this work?

  • verywearypaul Paul Sturgess (@verywearypaul) reported

    @O2 I cancelled contract within the 14 days and just received a bill for whole contract despite having made countless calls. Looking like ofcom for me as well. Disgusting service.

  • MandTweets Amanda Bailey (@MandTweets) reported

    @O2 Yes to texts, data and signal, yes it’s the same when I switch.

  • scoobyhugh8 Hugh Toner (@scoobyhugh8) reported

    @O2 I’m needing help and@no one seems to be interested

  • PhilTonks2 Phil Tonks (@PhilTonks2) reported

    @O2 DY8 Wordsley has had 2G for years. Struggled to even get a text out yesterday. Years of complaining, years of saying "there's an issue", then "it's fixed", when it clearly isn't. Even the guy in the o2 shop said "I wouldn't believe anything they say" when I told him....
