    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • 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

  • 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

  • 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.

  • 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

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) 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

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

    £105.03 A MONTH AND FOR THE LAST 6 MONTHS NO NETWORK !!! @O2 DO BETTER

  • 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

  • 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

  • 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

  • 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.

  • 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.

  • mike_johnson Mike Johnson (@mike_johnson) reported

    @virginmedia @O2 I'm bothered by this - I left O2 when they refused to give me a working phone and left me uncontactable. I'd have been able to see my grandmother before she died if they'd provided any kind of proper service.

  • kingofbumpers NHF (@kingofbumpers) reported from Chestfield, England

    @O2 hi, the last two days I have been showing no signal on and off , is there a problem ? Postcode CT5

  • Veronica_Strain Veronica Strain (@Veronica_Strain) reported

    @BLFCxx @Chriss_m @O2 I stayed with Virgin long enough to wriggle out of the contract with barely an ounce of sanity left. TV - never had the correct channels, phone - connected to someone elses number of 3 mths. Genuinely horrible company.

  • jhturner108 John Turner (@jhturner108) reported

    @O2 @virginmedia I can't say I'm overjoyed to have my device associated with the tax avoiding Tory supporting Mr Branson. Could call the merged network Virgin-O₂-Media for Information Technology or VOMIT for short

  • KatyCutprice Catherine Hodgson (@KatyCutprice) reported

    Hello @O2 I am struggling to help a senior family member. Their pay as you go balance seems to have been deleted and the number is deleted too. ( due to inactivity?) I need to get them a pay as you go sim that a balance can be kept on for emergency use only?

  • sheilaclark00 Sheila Clark (@sheilaclark00) reported

    @O2 @virginmedia I am a happy O2 customer and have been for over a decade. I used Virgin Media for a month and tried to get out of the contract due to terrible internet connectivity, but they forced me to stay for contract duration, or pay a penalty. Let’s hope O2 customer service prevails.

  • ellrbrown Elliott Brown (@ellrbrown) reported

    @O2 I first joined BT Cellnet in 2001, before it became O2, so almost a customer for 20 years.

  • GreenLe69138272 GreenLeave 💙 (@GreenLe69138272) reported

    @Veronica_Strain @O2 My thoughts exactly. Can’t think of a worse idea than teaming with Virgin Media ! Dreadful customer service, took 6 mths to get a refund after terminating my contract with them & they are only able to do this by cheque, really?! I’ll probably leave o2 & move fully to BT now..

  • MattyBx9427 MattyB (@MattyBx9427) reported

    @SkyHelpTeam @O2 What IS THIS Gone Into Portsmouth For The Day 3G 3BloodyG In Portsmouth This Is Rubbish @O2 Don’t Even Make Me Get Started About Signal At Home Speeds Here 0.32 MBPS Down

  • EvilSheepie Sheepy (@EvilSheepie) reported

    @O2 @virginmedia A bit disappointed and nervous. I love O2 and have never had any issue but Virgin have abysmal customer service, please don’t take their business model for customer service.
