    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

  • 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

  • cove123 mark nicolson (@cove123) reported from Welwyn Garden City, England

    @O2 opened app to use bacon sandwich offer local greggs not open yet for some reason @GreggsOfficial Wgc poor

  • 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

  • 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.

  • MANLIKENAIJA NAIJA BOI (@MANLIKENAIJA) reported from London Colney, England

    @O2 worst bloody network on the planet 6 FREAKING MONTHS I HAVE NOT BEEN ABLE TO USE MY PHONELINE DIE TO A MAST PROBLEM AND I AM STILL FORCED TO PAY FOR IT AND THEN HAVE TO PAY FOR ANOTHER NETWORK SIM JUST TO STAY AFLOAT KMT NEVER AGAIN

  • 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

  • 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 👏.

  • shazzstevo Sharon Stephenson (@shazzstevo) reported from Enfield Lock, England

    @O2 My calls keeps dropping. This has been happening for several days now. This is really poor service. This is in the Enfield area

  • 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

  • jasonmackenzie Jason MacKenzie (@jasonmackenzie) reported from London Colney, England

    Is there a hashtag for awful customer service from @O2 and/or @DHLParcelUK ? Asking for a friend.

  • peterives50 Peter Ives (@peterives50) reported from Enfield Lock, England

    @O2 Happy Monday to everyone but O2 who still can't sort out my text and calls problems after at least a month 😡

  • 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

  • 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

  • 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

  • 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. 👌👌👌

  • PieFaceMark mark (@PieFaceMark) reported from London Colney, England

    @O2 hello. I have just moved over to O2 and am considering buying a phone from the company Oneplus. I have read that Oneplus phones don't work with the O2 5g network, is this correct? I don't want to buy the phone then realise I can't receive 5g. Thanks in advance

  • Jamesba66061676 James baxter (@Jamesba66061676) reported

    @O2 In my situation all my calls are going to the voicemail and there is no way I can get support from customer services. Shocking, no wonder why customers are switching between telecos

  • nailheadparty 📻 GRAVEYARD MAN (@nailheadparty) reported

    does anyone know a more reliable phone network than @O2? sick of their flaky useless bullshit

  • N_J_Redman Nick Redman (@N_J_Redman) reported

    @O2 Tried all that but still very little signal.

  • hayley_ou Hayley Ou 💙 (@hayley_ou) reported

    @O2 No! Just an email saying bad news on the 27th telling me my pre-order is out of stock. Not a single update and no one will confirm delivery. What is just as frustrating is why no one at O2 will answer my question “why did you allow me to place a pre-order in the first place?”

  • N_J_Redman Nick Redman (@N_J_Redman) reported

    At home today and both my home WiFi with @TalkTalk is down and my mobile with @O2 also very very slow. Taken me around half an hour and several attempts to post this

  • PaulgPowell Paul Powell (@PaulgPowell) reported

    @MichaelBratley @O2 I've had the same issue and still no fix date 😡

  • SJ_OXO SJ. (@SJ_OXO) reported

    @O2 guys I haven’t had network since Monday and now it’s now Friday and it’s still down. My kids school can’t even contact me if somethings wrong this isn’t good enough!

  • desouza1994 Jace De Souza (@desouza1994) reported

    @O2 worst company to deal with. Customer service is absolutely shocking! Glad I’m no longer a customer of yours and when I finally rectify this latest howler from your company I can finally turn my back on you for good!

  • mitchfriedman5 Mitchell Friedman (@mitchfriedman5) reported

    @O2 how can someone actually contact customer service? the MyO2 app is completely broken and doesn't connect with an agent, and there isn't a phone number/live chat on the website.

  • Samanthahatton9 Samantha Hatton (@Samanthahatton9) reported

    @O2 worst customer service I have ever received. No intent on keeping a customer of 8 years, no help! Now leaving for @EE
