Latest outage, problems and issue reports in Blackwood and nearby locations:

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

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

  • 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? :-(

  • 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" 🙄😡

  • 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?

  • 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?

  • 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.)

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

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

  • 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!

  • 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. 😖

  • 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.

  • 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 👇

  • 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.... 🙄

  • 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

  • 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

    (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...

  • 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?

  • 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?

  • 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

    (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...

  • JamesLark2 Cllr James Lark (@JamesLark2) reported

    @Elksy91 @O2 There all terrible. Spent hours dealing with Virgin . Finally won though and down to sheer persistence

  • Tom_Courtney_7 Tom Courtney (@Tom_Courtney_7) reported

    @Ceeeemaaaaannnn @EnglandRugby @O2 Coles is another Saints lock, don’t know much about him really, seems handy but wouldn’t have though him about Laumchbury/Wells/Martin/Green, especially not with Saints issues at scrum time when the engine room will be a contributing factor despite props getting all the blame

  • Tankslider James Cameron (@Tankslider) reported

    Hi @O2. When I ring up to discuss options that include me leaving after 28 years, your operative just cutting me off when passing me to Customer Services helps neither my mood nor the likelihood of retention.

  • MaxDavi84377725 Max Davidson (@MaxDavi84377725) reported

    @O2 Phone stolen, requested sim block, went to pick up new one the next day as directed... they said my sim was now stuck in the system for 3-5 working days. Some people need their phones for important things like internet banking! Shockingly poor performance!!!

  • JuJulesberry Jules 💙 (@JuJulesberry) reported

    @O2 I have been a customer of your forever with no complaints but since changing to a sim only contract a few weeks ago I never seem to have data coverage anywhere whilst out and about. Please help

  • deutsch_scot JM (@deutsch_scot) reported

    @O2 Thank you for the checker. However this suggests that the mast in Manchester has been down since at least Saturday. Also, the one near Preston Hospital has been having ongoing issues since 30th August!!! What are you doing to resolve this & give us the service we’re paying for?

  • rhiannon_writes Rhiannon M (@rhiannon_writes) reported

    Hi @O2, I've been trying to cancel my contract for 6 months now with no success. Hours on the phone, DMs not answered. Haven't used the contract since end of March, yet you insist I still owe you. Can somebody please get in touch to sort this out?

  • jxmes_v jxmes (@jxmes_v) reported

    Ermm @O2 what’s going on with the signal in north devon?? Literally nothing for me or my mum on Tesco mobile?

  • HJDMISTASSAMIB Emz_1703 (@HJDMISTASSAMIB) reported

    @O2 why are you using DPD for your deliveries? Absolutely useless. I've just emailed a complaint to you guys after years as a customer, any idea how long it usually takes them to respond?

  • CLEVERCLOGS_SI SIMON WELSH (@CLEVERCLOGS_SI) reported
