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

  • 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

  • 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

  • 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

  • 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.

  • 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. 👌👌👌

  • 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 👏.

  • fierce_unicorn 🦄 (@fierce_unicorn) reported from Enfield Lock, England

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

  • 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

  • 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

  • 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

  • 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

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

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

  • 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

  • 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

  • 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

  • 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.

  • 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.

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP please

  • FACTteam TitsUpproduction💪💙 (@FACTteam) reported

    Having awful problems with @O2

  • The1andOnlyPK Paul (@The1andOnlyPK) reported

    @BorisJohnson @virginmedia @O2 Much more expensive Sims to pay for this "free" service. If you don't travel or won't travel a lot. You will save a lot of money by using another provider

  • itskyleflamson Kyle F (@itskyleflamson) reported

    I’m rather concerned about @TelefonicaUK / @O2 trying to oppose #PrivateRelay for #iPhone. Almost like they dislike the idea of customer privacy, which sounds suspiciously like @Facebook disliking user privacy so they can sell our data to advertisers.

  • vallendemain Val Lendemain #FBPE #FBPPR (@vallendemain) reported

    @NadineDorries @virginmedia @O2 Just how ******* stupid do you think we are, Nadine Dorries?

  • apluspj Ali PJ (@apluspj) reported

    @O2 I went to Caffè Nero to use my coffee voucher, downloading voucher just before I got to the door as reception issues inside the shop but they had locked the door as they were closing an hour earlier than advertised. Is it possible to cancel my voucher so I can use it 2moro?

  • BlokeOfWords Mark Williams (@BlokeOfWords) reported

    @NadineDorries @virginmedia @O2 That is simply a lie. In any case, you could issue the same mandate, but you don't because it might stifle Party donations.

  • TomSmit64578800 Tom Smith (not that one) (@TomSmit64578800) reported

    @O2 Things like this are what keeps me as an O2 customer

  • FifeArab Ali Watt 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇸🇪🇺💙 (@FifeArab) reported

    @NadineDorries @virginmedia @O2 If you and your corrupt mob of fellow idiots hadn’t dragged us out of the EU, mobile roaming wouldn’t be an issue.

  • UK_Centrist John 💙 🇬🇧 (@UK_Centrist) reported

    @BorisJohnson @virginmedia @O2 Good PR for them, but no assurance for consumers it won't change in future. A far worse deal than the one we had where it was mandated. But we have a truly corrupt and awful government.

  • Judithrhion Judith 💙#FBPE#SackReesMogg (@Judithrhion) reported

    @NadineDorries @virginmedia @O2 But rather than address this narrow problem, the UK government took a deregulatory approach and removed any limits on retail roaming charges.
