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

  • 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...

  • 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?

  • 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

    (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...

  • 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" 🙄😡

  • 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.)

  • 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?

  • 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

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

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

  • 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.

  • 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.

  • 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

  • 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. 😖

  • 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.... 🙄

  • 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!

  • KamDhaliwalx Kam Dhaliwal (@KamDhaliwalx) reported

    @O2 upgrade you but send out imaginary phones - called x6 times to be fobbed off!!! Been waiting by the front door since Fri for my phone to arrive. "Not our issue, speak ro DHL"

  • Anthony15665779 MCFCANT88 (@Anthony15665779) reported

    @O2 @kwhite_96 Problem is your obviously lying to your customers and it's not fair. Your customers pay a lie t of money for a service they can't use properly I'm having these issues too and I keep getting told that a mast is down..

  • Anthony15665779 MCFCANT88 (@Anthony15665779) reported

    @pds1980 @O2 Absolutely horrible o2 isn't it?

  • WorstOfBrighton WORST OF BRIGHTON (@WorstOfBrighton) reported

    @o2 Still waiting for an answer! Could o2 customers please retweet: Whats the customer complaints email address? Don't worry canceling the CONtrack.

  • heygraeme graeme (@heygraeme) reported

    14 upgrades and I’m firmly into my 14th experience of waiting a month or longer for my new phone to turn up - which has already been paid for. I really find it hard to accept that @O2 have the same issue every damn release. It’s embarrassing for them, from a customers POV.

  • andrewmorgan82 Andrew Morgan (@andrewmorgan82) reported

    @gethinbach @O2 Worse network out there I was only with them for 12 months and had more problems than any other network… Vodafone I have found the best

  • kerrie74055076 kerrie (@kerrie74055076) reported

    @O2 wouldn't let me redeem the code for Apple Music says I already used it but I haven't how can you help me with this please

  • yamez_explores Yamez Explores (@yamez_explores) reported

    @O2 any chance I can claim money back on my contract since your signal seems to be absolute garbage wherever in the UK I go these days?

  • warelephant1919 Winston Smith (@warelephant1919) reported

    @O2 can you explain why virgin gave me an O2 sim they said was free, you charged me £50 and promised me a refund but never gave me it. Are you just keeping my money? Nice scam you've got going there.

  • _i4ani You planned this (@_i4ani) reported

    @connordoner @O2 I have just been on the phone to O2. They have told me that message should not be there. I have been out of the area where the mast is working and still no service.
