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

  • 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

    (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

  • 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?

  • 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.

  • 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.)

  • 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.

  • 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

  • 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.

  • 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?

  • 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

    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" 🙄😡

  • 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

    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

  • 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?

  • 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?

  • animusbaby Hannah (@animusbaby) reported

    @O2 very disappointed today. Ordered upgrade for collection for today, received text to say there was a problem at 9:40am to say I wouldn’t be able to collect. No word since. Wanted to set up before new work week as very busy teacher. 😡

  • Labour4Animals 🌹#LAWS4Animals 🐾🦁🦊🐘🦛🦒🐒🌿🌳 (@Labour4Animals) reported

    @PeteCityPrice @O2 That is awful - surely they can roll back

  • TweetyPie100 Joanne Whitfield (@TweetyPie100) reported

    Been an @O2 customer for 20+ years and contract just ended. Absolutely disgusted to find out, should I take a new contract with them, my bill could increase by at least 9% in April. 😠

  • ChrisBlaylockDJ Chris Blaylock ⚪️⚪️ (@ChrisBlaylockDJ) reported

    @HollyIlling @O2 I lost a bet because I couldn’t cash out as I had no signal from 2.15 -5pm Also o2 🤬

  • JohannaHinton Johanna Hinton💙 (@JohannaHinton) reported

    Hi @UswitchUK Why can’t I seem to buy a sim only contract on your website? It tells me to call @O2 & then they tell me they can’t do anything but who else am I supposed to ask for help? 5 40 minute phone calls to @O2 around this week & they’re making out the offers aren’t legit…

  • lincolnspidey fern 🌿 (@lincolnspidey) reported

    @O2 hi, how can i cancel my contact? i’ve paid off my device

  • PeteCityPrice Pete Price (@PeteCityPrice) reported

    @Labour4Animals @O2 I’m so upset I can’t explain how bad I feel

  • PeteCityPrice Pete Price (@PeteCityPrice) reported

    @rachaeleknox @Labour4Animals @O2 They have never been wiped before

  • SGall78 Simon Galloway (@SGall78) reported

    @O2 Hi guys, sorry for another tweet but could you help me with adding Amazon prime video as my extra please? I've had several attempts but every attempt has been to no avail.
