  • 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.

  • 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

  • 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

  • MarkstanYoutube Mark Stanford (@MarkstanYoutube) reported from Luton, 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 👇

  • 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!

  • 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

  • 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 👏.

  • 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

  • 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

  • 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

  • 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.

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • 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. 👌👌👌

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

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

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

  • 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.

  • 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

  • husheen76 Mark 🇮🇪 (@husheen76) reported

    @O2 hi. I’ve had no signal since yesterday morning? Tried manual selection and it’s not offering any network at all.

  • AnnieFordWilko Anna Wilkinson (@AnnieFordWilko) reported

    @O2 advice pls, for weeks/ months I've had hardly any signal, NP44 postcode,apparently there is a mast not working nearby, pls reduce my bill/improve my signal, I am so fed up. I've been with you for about 25 years & am thinking of going elsewhere. Can't make a simple call 😪😠

  • BrentfordHarry Harry (@BrentfordHarry) reported

    @O2 your service is a ******* joke.

  • steveblower1 steve blower (@steveblower1) reported

    @O2 can someone at O2 come back to me as to why you are trying to charge me for a call outside my tariff when I have made no call???? Tried contacting but no response as yet. Love to say this an isolated issue with O2 but

  • Andy_TheGrouch Andy (@Andy_TheGrouch) reported

    So bored of @O2 being unable to maintain 4G or a phone call wherever I go. ‘No network problems in your area’ well there clearly is. Garbage.

  • Nalfy5 Nalfy (@Nalfy5) reported

    @O2 Yes, as I said I have been through the entire support process 3 times, even again this morning yet nothing is being done to fix it, just a loop through the same support processes

  • mreyetee Thomas Burton (@mreyetee) reported

    For three years I have been saying @O2 need to revisit the prices of their Data Bolt-ons. It is never more true than now. They're wildly prohibitively expensive. I need an extra 10-15gb once a year. I end up buying a random PAYG sim and putting a tenner on for data hotspot

  • JamesJansson85 James Jansson (@JamesJansson85) reported

    @O2 no help, no communication, no cooperation. How do you get it soo wrong?

  • Hathor32563459 Hathor (@Hathor32563459) reported

    @O2, when an agent was asked if O2 thought people with mental illness were stupid, the agent said 'I don't deny that'. That proves 02 policy on mental illness.

  • JamesJansson85 James Jansson (@JamesJansson85) reported

    @O2 MS disabled with no working services and no help or explanation as to why. Not good enough
