  • 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.

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

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

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

  • 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.

  • 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

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

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

  • 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.

  • 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

  • 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

  • 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

  • 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 👏.

  • 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

  • 2SortsNorfolk Darren (@2SortsNorfolk) reported

    @o2 Can you sort out your data network please? I’ve not long upgraded on the back of you telling me 5G is the way. It’s worse than 3G! Anywhere built up, the problem arises. Phone is unusable when it’s like this. It’s not a new issue either. It drags on and on.

  • valleycommando1 pponty (@valleycommando1) reported

    @O2 Losing the will to live with new O2 sim. Every single card I've got declined for £10 top up via web or phone. About to give up and try vodafone. Very poor indeed.

  • Merse2506 John Mercer (@Merse2506) reported

    @O2 why am I still waiting for O2 to sort out why i cannot access the O2 APP? Its been 6 weeks of my new phone and tjet are quick to take tje money but service is shocking. As a VM custimer its now double shockung customer service. I need to escape fron these contracts

    Hello @O2 Team, any news on a replacement mast near The Plain in Oxford now the Sainsbury's building is going? 5G/4G reception is awful now in the area.

  • RonnyAllan1 Ronny Allan (@RonnyAllan1) reported

    @O2 worst customer services in the world!

  • anthonyden1 ant / אנתוני (@anthonyden1) reported

    In early November the openly antisemitic pieces of trash bob vylan will play at 02 venues in Leeds Manchester Glasgow and London If they are allowed to play these “gigs” they will bring the name of 02 into disrepute and I will cancel very contract I have with @O2.
