  • 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.

  • 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.... 🙄

  • 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?

  • 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?

  • 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?

  • 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...

  • 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

  • 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

    (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.

  • 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? :-(

  • 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!

  • 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.)

  • 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

  • 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

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

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

  • 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?

  • 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. 😖

  • 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

    (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...

  • vanessam9363 Vanessa Bunce (@vanessam9363) reported

    @O2 still not had my query resolved. Now had automated phone call saying pay or you will cut phone off... appalling service!!

  • samkir82 sam (@samkir82) reported

    @O2 Thanks, we got in early and spoke to helpful angels, that's what you call service 👍🏼

  • dgturvey David Turvey (@dgturvey) reported

    31 hrs have passed since I reached out to @O2 Social Media Support Team to resolve OTP message failure. I have provided all information requested but received no information back regarding any progress, resolution or likely timing of either. This leads me to obvious conclusions.

  • agust_yoonji DelOnEarth is in 🇰🇷 (@agust_yoonji) reported

    Hey @O2 why the hell can’t I login to my app to top up my PAYG sim?

  • s_w_photograph Stuart Williamson Photography (@s_w_photograph) reported

    @O2 got any signal issues in the BA16 area? No signal here

  • nuttyrichard richardhutchins (@nuttyrichard) reported

    @O2 Why are you selling my private details to outside companies without my permission which I’ve never granted

  • paulhayward200 Paul (@paulhayward200) reported

    @O2 Oh good Iam not the only one who thinks that O2 is the worst network ever. Dreadful service and appalling customer service .

  • railwaychaplain Liam Johnston (@railwaychaplain) reported from Rugby, England

    @Paul_Martin1970 @O2 The reception says 4G. They will probably say there is work being done on the transmitter. But it's been a recurring and frequent issue for the last three years but it's getting worse. I think it is to push people to get 5G phones.

  • hunnybee100 Mel (@hunnybee100) reported

    @O2 ..and when I said that I'd feel more comfortable doing that just in case, he became aggressive and condescending and said "are you REALLY going to ring back when you could just tell me the answer? I've literally never dealt with a customer who had an issue like this" 😑🤯 (2/2)

  • runningrach71 • Rachel • 💙🇺🇦💛 (@runningrach71) reported

    @O2 I will be raising a complaint with you about this whole shambolic experience. I didn't even chose you as a provider, I was transferred to you from @virginmedia - what a mistake that was! I will actively discourage anyone from using you. Woeful!
