    @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

  • 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

  • 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.

    @O2 merlin pass code is not working, can you help?

  • 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

  • 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.

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

    @pascall21 @O2 Every year, worst service award goes to @O2

  • so_akin Oğuzhan (@so_akin) reported

    Heyy @O2 — I haven’t been able to use mobile internet, make calls, or send texts for 3 days. Are you planning to do something about this? I can’t see any explanation about the problem, maybe you don’t know but we have a big problem.

  • Quantum_android Rob (@Quantum_android) reported

    @O2 So, I'm trying to sign in to my o2 account to pay a bill for a product. Can't do that unless I sign up for ANOTHER account with VMO2. Can't sign up for VMO2 as I do not have an o2 phone number. Also can't link my virgin account as I don't have the account number.

  • ndrewskinner Andrew Skinner (@ndrewskinner) reported

    @virginmedia @O2 @DisneyPlus what a shambles. Can’t access O2 app to manage my Disney acct, VM no idea why, O2 say app is down as last week’s update to merge it with VM has gone wrong, so wait till it’s fixed. O2 can’t help either as their access is also down #itsm #customercomms

  • AlunOwen6 Alun Owen - (@AlunOwen6) reported

    @O2 your mobile service across the country is at best, patchy. Shocking considering how much you charge monthly customers

  • VenningBellasis Venning Bellasis (@VenningBellasis) reported

    @O2 I am not able to receive any text messages from anyone on the EE network. This is the second time it's happened. Is there anything you can do?

  • BlackburnJulian Julian Blackburn (@BlackburnJulian) reported

    @O2 what on earth have you done to your App. Absolutely useless since you are now virgin O2. Never had issues accessing the app but now being asked to verify my email address and can then not get in with the verification. Awful!!!! Ditch Virgin and go back to what you had!!!
