  • 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 👏.

  • 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.

  • 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

  • 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.

  • 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

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

    @O2 I need help ASAP please

  • 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

  • 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

    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

  • 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

  • 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. 👌👌👌

  • 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

  • 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.

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

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

  • 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

  • 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

  • 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

  • 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

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

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

  • 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

  • KarlWatkins15 Karl Watkins (@KarlWatkins15) reported

    @leonakate @O2 @peterkay_co_uk My goodness! I think the 02 are still trying to support their broken roof fund from a couple of years ago

  • burke1412 Andrew Burke (@burke1412) reported

    @O2 This is a embarrassing poor show by o2 I am seriously considering moving my family from o2 to another network your treatment of customers is becoming worse over time and the benefits of being a priority customer are certainly questionable based on the Peter Kay shambles

  • midlandnautique Midlands Nautique (@midlandnautique) reported

    @O2 Unbelievable o2 are a joke ! Still can’t get on the app. So bad for customer relations. Business contract up next month . EE looking forward to joining you #EE #O2 #peterkay

  • KirstynThomas14 Kirstyn Thomas (@KirstynThomas14) reported

    @O2 Your app is still broken yet your celebrating your biggest failure to custoners. Get the app back online

  • SueDown51169163 Sue Downey (@SueDown51169163) reported

    @KirstyLBx @O2 They sold out and that's why it gone down

  • irishangel84 Shauna (@irishangel84) reported from Belfast, Northern Ireland

    @O2 Don't care about Peter Kay tickets but I can't even get my Friday Greggs treat 🙈🙈🙈

  • karlemar7 drklem (@karlemar7) reported

    @O2 Still down this am

  • Johnson9Michael Michael Johnson (@Johnson9Michael) reported

    @O2 An apology for the absolute shambles would be nice. Websites not accessible, apps not working, invalid codes. To see the tickets on sale now for huge amounts is just an insult.

  • Nicola_M91 Nicola(murray)Edger (@Nicola_M91) reported

    @O2 Not being funny @O2 but what’s the point of having the priority perk if only some of your customers can access it!! 😡 totally get technical issues happen but surely that would effect ALL users and not just some. I feel their should be another pre sale!!

  • Kellyh2203 Kelly Heaton (@Kellyh2203) reported

    @O2 How can priority still be down this morning , yet you have sold your tickets 🤔🤔🤔 i just want my Greggs coffee 😪
