  • 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

  • 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!

  • 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.

  • sarlpar Sarah (@sarlpar) reported from Henllys, Wales

    @O2 It’s been going on for months, I have friends dotted around NP44 and they all struggle making phone calls as they keep dropping out, it’s not something new it’s an ongoing issue. I’d change if I wasn’t tied in and I think you’ll find other would too if they could. So frustrating

  • cymboi MH 🏴󠁧󠁢󠁷󠁬󠁳󠁿🏳️‍🌈🇪🇺 #yescymru (@cymboi) reported from Victoria, Wales

    @O2 How is that great value for a customer, when a sim only package is £30, yet its £35 when you purchase it with a phone?

  • uncriticalsimon Simon 💉💉💉🐉 (@uncriticalsimon) reported from Newport, Wales

    @jasonmackenzie @O2 OK I once had trouble with EE (not for the mobile service but when I switched to broadband), it got so bad that I decided to go back to Sky. (NB now with TalkTalk, also not great for customer service but OK if nothing goes wrong.)

  • stuomac88 Stuart Maclean (@stuomac88) reported from Abertillery, Wales

    @O2 supposed to have had a bill credit applied to my account due to mast issues. Can you check this for me as still not showing on my o2?

  • sarlpar Sarah (@sarlpar) reported from Henllys, Wales

    @O2 your coverage in the Cwmbran area NP44 is shocking, no end of people on O2 post about the poor signal especially around the Llanyrafon and Henllys/TyCanol area. When we ask about if there are any signal issues we’re told there’s not, Vodafone, EE and 3 work prefect. 😖

  • cymboi MH 🏴󠁧󠁢󠁷󠁬󠁳󠁿🏳️‍🌈🇪🇺 #yescymru (@cymboi) reported from Newport, Wales

    @virginmedia @O2 Why is your Hotspot so poor? Never connects!

  • 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

    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" 🙄😡

  • SamHallWales Sam Hall 🏴󠁧󠁢󠁷󠁬󠁳󠁿🐾🐾🌈 (@SamHallWales) reported from Cwmbran Central, Wales

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • 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

  • 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

  • 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?

  • Shaunalj93 Shaunalj (@Shaunalj93) reported from Ferndale, Wales

    I need some help @O2. I was told I can get o2 open as I have a @bluelightcard but when I’m trying to register it online it is not accepting my device.

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

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

  • BigDogWrestler 🌈 Champ (@BigDogWrestler) reported from Cwmbran Central, Wales

    @O2 why is my signal often very poor and I mean often and very very poor?

  • 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...

  • Taxiboi3583 Adam Smith #BlackLivesMatter (@Taxiboi3583) reported from Beechwood, Wales

    @O2 Totally ignored my actual question, do I get a rebate on my bill if I experience technical issues?

    .@O2 Uk are really pushing out the boat to help users in Tq3 again, excuses excuses

  • chrisfridge180 Chris Maguire (@chrisfridge180) reported

    @O2 it states on your web page to request an esim to pop into a store and they will be able to get you one. I popped into a store today to be told that they couldn't and tried to direct me to the local phone repair guy! I need to esim my o2 SIM as a 2nd line in my phone. #help

  • sousuke_04 sousuke (@sousuke_04) reported

    @Hammondhamster6 @O2 Did you sign in via AXS as the sign in button won’t even work for me?

  • girl_adventurer Katie MacKinnon (@girl_adventurer) reported

    @O2 I'm still waiting on the code for my gift card almost a month after signing up to a new (unlimited) contract and phone (samsung flip). Your rewards team have stopped replying to my emails to fix the problem as well. How are you going to fix this?

  • kirstybabyxo Kirsty 💕 (@kirstybabyxo) reported

    @O2 are there problems with the o2 priority app?

  • stridesshoes STRIDES (@stridesshoes) reported

    @O2 You have ALL details on live chat and you've been DM'd please read first and get back to me. I am the mother and bill payer of the person using this number - appalling customer service

  • SionedElin94 Miss E 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@SionedElin94) reported

    @O2 what is going on with signal?! No signal at all almost all day.

  • Hammer Hammer (@Hammer) reported

    @endless_psych @O2 Are you in town? If so, it’s probably a capacity/bandwidth issue - same as you get at the rugby.

  • J0eH0lmes Joe Holmes (@J0eH0lmes) reported from Salford, England

    @O2 my phone is saying no sim so I have zero signal or data to call or text you. Any chance of getting someone to give me a ring to sort out a new sim card?

  • HulmeDanny Danny Hulme (@HulmeDanny) reported

    @O2 Really disappointed with o2. Been a customer for 12 years and you cut my phone off 3 days in a run! Bill paid in full every month. Called up every day and I'm being told its a computer automatically doing this. 3 days of work I've lost. No help at all.
