  • acdavies67 anthony davies 🇾🇪🔰🏴󠁧󠁢󠁷󠁬󠁳󠁿🇺🇦 (@acdavies67) reported from Barry, Wales

    Well I've gotta be honest,never again will I take another phone contract out with @O2,wherever I go in a 50 mile radius of my home,my signal is **** and they called me last week offering me more data,more data ?,*******, i can't get anywhere near my data limit now ffs 😡😡😡😡

  • CharlBalcombe Charlie Balcombe (@CharlBalcombe) reported from Cardiff, Wales

    @O2 hello! I forgot to put my UNiDAYS on when purchasing my new phone contract and I’m struggling to add it on after, is it possible you could help me with that please? :-(

  • davesouthphoto Dave South (@davesouthphoto) reported from Cardiff, Wales

    If I had a £1 for eveytime @O2 text me about my local mast being down. I wouldn't have to pay for my contract anymore. Wearing thin now guys.... 🙄

  • BigDogWrestler Super Blue Eye Dog (@BigDogWrestler) reported from Cardiff, Wales

    How can @O2 sponsor the World's most popular concert venue as in @TheO2 but can't give me a decent signal for 50% of my day?

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (4/4) ...as being the fault of an automated system, without any recompense or any attempt to suggest that they can improve, is horrifying. I feel almost constantly threatened, intimidated, and abused by @O2 due to an issue that they caused, and they are making no attempt to fix.

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (2/4) ...from @o2 dated TWO DAYS after the issue was, I was told, cleared up. A call to #O2 #AccessForYou this afternoon shows the issue is cleared up and the letters are auto-generated because payments can take up to 48hrs to register with O2...

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (1/4) Not a week after I was horrifically abused by an @o2 #CustomerServices agent, and even after I settled the payment issue (ongoing problems with #O2 automated systems since last Aug/Sep) that very day, I have today received three consecutive threatening/#legal letters...

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    30 mins on hold to @O2 customer services, spoke to an agent who has now put me on hold to speak to transfer me to #CustomerServices...so God knows who the hell I got through to 🙄😡 #FirstWorldProblems

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    If it wasn't for all the free benefits I got with @O2 Priority, I'd ditch them. Their #CustomerService is abysmal. It's like being in some weird kind of abusive relationship: "we'll treat you like **** but give you lots of free stuff so you'll want to stay with us" 🙄😡

  • Lea_May_ Lea French (@Lea_May_) reported from Cardiff, Wales

    @O2 don't recommend upgrading with o2. Terrible service, can't speak to anyone on the phone and waited for over a week for my delivery that was due on Monday!

  • divyaparikh_ Divya (@divyaparikh_) reported from Cardiff, Wales

    @O2 Thanks for all the help @O2! Just got a call saying matter has been resolved.

  • ChrisEddy_7 Eddy 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@ChrisEddy_7) reported from Cardiff, Wales

    It’s come to something when you can get 4 bars of 4G signal walking between Benidorm and Albir in Spain but can’t even get 3 bars of 3G signal in Cwmbran South Wales 👀 @o2

  • BristolOli Bristol Oli (@BristolOli) reported from Cardiff, Wales

    @BS3Rob @O2 @WBA Been horrendous for weeks - Can’t complete a call without having to call back numerous times - BS3 probably the worst of them all but M4 corridor from Cardiff to Bristol is a close second

  • BristolOli Bristol Oli (@BristolOli) reported from Cardiff, Wales

    @BS3Rob @O2 Glad it wasn’t just me - No signal anywhere near the ground

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    This weather properly has me over a barrel. Mistreatment by @O2 properly has me feeling down. My #CovidVaccine pain is bad. Some days the demons are just too much to battle...but today is not one of those days. Rest, relax, refocus. #MentalHealthMatters #BipolarDisorder

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (1/3) Sad to say that @O2 are now trying to charge me for a service never used, when I cancelled a mis-sold contract within the 14-day cooling-off period. Almost two months later they're now saying they're going to charge me a late payment fee, plus the bill...

  • themarkhawkins Mark Hawkins (@themarkhawkins) reported from Barry, Wales

    @viv_wilson @O2 I am in CF62 area, I haven't been able to get more than one bar for years, forget 3/4g Only keep it as I get a good signal in work.

  • PattersonLela1 Lela Patterson (@PattersonLela1) reported from Barry, Wales

    Hi @O2. If you received a notification that a sound was played from my phone, please don’t worry. I was just testing out the Find My app on my iPhone, as I’ve never used it before, so I just wanted to check it out and see how it worked. Thank you and sorry. :)

  • PattersonLela1 Lela Patterson (@PattersonLela1) reported from Barry, Wales

    @O2 I didn’t receive an alert and neither did my family. It’s a fantastic idea, though! Are all Network operators doing this? :)

  • nopantsuk Nick Thorogood (@nopantsuk) reported from Llanharan, Wales

    @O2 my number should be ported to you today that I requested yesterday morning. I’ve had no confirmation texts or emails though and number still on old network. Any ideas?

    @O2 can you tell me where the option is? I can't find it. I am happy to look stupid! :)

  • bodge4uk Rob Lewis (@bodge4uk) reported

    Just been implied to me by @O2 customer “care” chat that engineers are working on small town signal issues. 🤬 are they! Pay for a data package but unable to use it and told “you don’t use much” NO WONDER! Then you tell me use WiFi. What’s the point in buying data? Sort it out!!!

  • Rachel_Coombs Rachel (@Rachel_Coombs) reported

    @O2 does o2 not work in Brighton?? No signal all day. Phone claims I have 5G but no internet. No o2 WiFi hotspots to connect to. Finally have connected to WiFi in cafe.

  • w0tts w0tts - Follow @gamefoliogg (@w0tts) reported

    @O2 you guys really need to look at your customer support, absolutely awful. Moved around to 3 different chats, I call your call centre and all you can hear is about a thousand people in the background, shouting, cars beeping going past the office.. what the hell is going on

  • Miss_Rhi_Rhi Rhian (@Miss_Rhi_Rhi) reported

    @O2 Hi. I need help logging into my account so I can update my email address. I no longer have access to that email account but can 2FA via my phone. What do I need to do as each time I try and login it send a link to the account I can't access. Thanks

  • graeuk Graham Martin (@graeuk) reported

    @O2 @giffgaff I'm on the Eurostar travelling back from Belgium. Signal tremendous all the way 5G /4G on Orange-B / Orange-F until I get to the UK when it keeps dropping and I get loading icons. Why in 2025 can't the UK have reliable signal throughout the country?

  • __d4nedison DAN 🍂 (@__d4nedison) reported

    Never been more disappointed and frustrated with a phone upgrade process than I have with @O2. About to call them for the MILLIONTH time and spend TOO long on the phone to sort out problems they've caused.

  • carolinemcg77 Cazz Friel (@carolinemcg77) reported

    @virginmedia @O2 down again it’s been off now for 2 days sort yourself out service is awful Northern Ireland 🤬🤬🤬🤬

  • Wolfpack_J5 Patriotic_Wolf (@Wolfpack_J5) reported

    @VMO2News @virginmedia @O2 Funded by us customers who you cannot provide a decent service too!!!!! 2 faulty phones in the past 12 months, and now refusing to accept liability for damage caused during a repair. No photographic evidence as requested, now got a case open with the Ombudsman 🤬🤬🤬

  • Wolfpack_J5 Patriotic_Wolf (@Wolfpack_J5) reported

    @O2 Summer freedom........where you can't even use the phone you're paying for, due to #O2 sending out faulty phones, and then refusing to accept any liability!!!!!!! The worst company ever to deal with, and the most incompetent "customer service" @LutzSchueler 🤬🤬🤬🤬🤬
