    @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

  • 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 👏.

  • 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

  • Atanvarne ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England

    @O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

  • 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

  • CCTVinCare 💜💚Care Campaign For The Vulnerable💚💜 (@CCTVinCare) reported from Gerrards Cross, England

    @O2 amazing customer service experience on your 202 called MARCO. 🙏

  • 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

  • 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.

  • 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

  • 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. 👌👌👌

  • 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

  • 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

  • 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

  • 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.

  • 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

  • davidluxton99 David Luxton (@davidluxton99) reported from London Colney, England

    Disappointing poor customer service from @dhlexpressuk who inform me of my parcel delivery at 10.40 this morning then send another message to inform me it will now be 6 days later! #DHL not fit for purpose as a #courier for @O2 as I will now cancel the order

  • 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

  • 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?

  • theandycooke Andy (@theandycooke) reported from Barnsley, England

    @O2 On the commute into Sheffield I had issues with signal, at time went to 3G (I can’t remember the last time I saw 3G with @EE). I also had some signal issues whilst at work in the centre of Sheffield & didn’t once achieve a 5G signal.

  • toxic77rose ⭐️ Miss T ⭐️ (@toxic77rose) reported

    Is there a problem with @tescomobile and or @O2?

  • lil_skyscraper_ Sarah ツ (@lil_skyscraper_) reported

    @O2 I’m going to upgrade when the newer version comes out, I’ll still be keeping the airtime tariff just trying to cut down my monthly bills.

  • stuart_fenton Stuart A Fenton (@stuart_fenton) reported

    Interesting email from @O2 regarding roaming. Previously your contract data package (unlimited in my case) was available across Europe and USA. Now capped at 25gb per trip. Vodafone doing the same. This is crap for biz travel, worse for family holidays

  • jwayne_1972 Jayne (@jwayne_1972) reported

    Hoping someone at @O2 actually responds to my partners complaint and resolves the issues ASAP. Have sent a DM as a last resort! Please check

  • Bobs_Burgers20 Smilesy (@Bobs_Burgers20) reported

    @O2 is there a reason your service has gone from completely fine to really **** in Wiltshire?

  • Life360 Life360 (@Life360) reported

    @SparklyG @O2 Hi, we are not seeing the DM from you. Can you please send another DM to Life360 only with the email address on your account and a description of the problem? Looking forward to hearing from you soon. Thanks! ~Kris

  • bossarocker Lou Armer 🦙 (@bossarocker) reported

    @O2 Lol, how hard is it to resend an email? It's only the links that need fixing. You should have done this yesterday as soon as customers alerted you to the problem. Anyway, it's all moot now as I won't be a customer of yours for much longer.

  • robinrimbaud Robin Rimbaud - Scanner (@robinrimbaud) reported

    @cassieldotcom @O2 No, Nick, that would never happen. I'm sure that was painted on the side of a bus somewhere!

  • toxic77rose ⭐️ Miss T ⭐️ (@toxic77rose) reported

    @O2 I'm a tesco mobile customer but my work tablets that are o2 were dropping out at exactly the same time
