  • 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

  • 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.

  • 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

  • gadgetgem Gem (@gadgetgem) reported from Barnet, England

    Missed out on my free sandwich this week @GreggsOfficial with @o2 due to the scanner being broken again. Went to next nearest greggs and they had no breakfast 😢 #o2priority #greggs #breakfast

  • 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

  • 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.

  • 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 😡

  • VictoriamariaC Victoria Clarke (@VictoriamariaC) reported from Walthamstow, England

    @O2 please can I ask why you have left a 76 women who has just lost her husband and undergoing cancer treatment without any phone service and no one is able to help. Absolute disgrace @lec1479

  • 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

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

    @O2 I need help ASAP please

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

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

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

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

  • 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.

  • 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

  • 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

  • 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

  • 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.

  • 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

  • Jennifer03017 Jennifer Ferguson (@Jennifer03017) reported from London, England

    @O2 when you press use now on the Priority Lane where is the code - I only have a screen with a timer counting down. I can’t see a code? Thank you xx

  • Miss_PSJ_ Paula. (@Miss_PSJ_) reported

  • karlax1x Karla X (@karlax1x) reported

    @O2 your insurance policies are a rip off loyal customer since 2016 and you decline a genuine claim!!!! Disgusting service

    @O2 when are you going to fix the signal in st helens town center im sick have having no signal been going on for months i work and live in town and not being able to use my data

  • Icarus691 Icarus69 (@Icarus691) reported

    @O2 why do you just cut off people wanting to query their bill? Are we expected to just pay and not ask questions? Customer service across the board is atrocious, not just o2. As long as they get paid, these massive businesses do not give a $&1/

  • ItsEdenExile 𝕰𝖉𝖊𝖓 𝕰𝖝𝖎𝖑𝖊 🖤 (@ItsEdenExile) reported
