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

  • 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.

  • PattersonLela1 Lela Patterson (@PattersonLela1) reported from Barry, Wales

    Hi @O2. If you received a notification that a sound was played from my phone, please don’t worry. I was just testing out the Find My app on my iPhone, as I’ve never used it before, so I just wanted to check it out and see how it worked. Thank you and sorry. :)

  • 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

    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

  • themarkhawkins Mark Hawkins (@themarkhawkins) reported from Barry, Wales

    @viv_wilson @O2 I am in CF62 area, I haven't been able to get more than one bar for years, forget 3/4g Only keep it as I get a good signal in work.

  • 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...

  • flowersshanice S H A N I C E (@flowersshanice) reported from Cardiff, Wales

    @O2 @Gropinvillain In all these years I’ve been with @O2 I’ve never ever had nothing for bro g a loyal customer, maybe it’s time I cha he networks after my contract is finished!!

  • 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" 🙄😡

  • PattersonLela1 Lela Patterson (@PattersonLela1) reported from Barry, Wales

    @O2 I didn’t receive an alert and neither did my family. It’s a fantastic idea, though! Are all Network operators doing this? :)

  • 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

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (1/3) Sad to say that @O2 are now trying to charge me for a service never used, when I cancelled a mis-sold contract within the 14-day cooling-off period. Almost two months later they're now saying they're going to charge me a late payment fee, plus the bill...

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

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

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    @O2 There’s delay then there’s rude. Been 92 working days or 128 days since I complained. @o2 are making it deliberately difficult to contact.

  • 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!

  • DennerSusan susan denner (@DennerSusan) reported from Cardiff, Wales

    @O2 Customer service shocking! No service on phone since 24th May, SIX calls made to your call centre to resolve issue - now being told to wait for

  • 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

    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

  • nopantsuk Nick Thorogood (@nopantsuk) reported from Llanharan, Wales

    @O2 my number should be ported to you today that I requested yesterday morning. I’ve had no confirmation texts or emails though and number still on old network. Any ideas?

  • LisaEdwards78 LisaEdwards78 (@LisaEdwards78) reported from Barry, Wales

    @O2 Hi there I have had a highly Sophisticated national insurance scam call from a number registered to your network. There was an automated message purporting to be from the national crime agency. Please can you investigate this number 07850058296

  • vsirnate Vasundhara Sirnate (@vsirnate) reported

    When I asked the customer service guy about this he said yes they use the site. He sounded nonchalant. Like it happened everyday. I am very alarmed. @O2

  • tony_sutton Tony Sutton (@tony_sutton) reported

    Paid for 24 hours of Data SIM with @O2 which was activated straight away and clock counting down. Never worked, even after many device reboots and trying various O2 profiles. Tweeted & DM'ed @O2 - no reply. 24 hours is expiring soon. Waste of money. :/

  • mcresswell75 matt (@mcresswell75) reported

    @O2 why is there always an outage in Derby when its heavy rain 😩

  • blue33313 colin lewin (@blue33313) reported

    @O2 what thf new customer trying to find no to talk to human impossible! Give up! Just lost new customer switching

  • micoolpaul Michael Paul | MicoolPaul 🇺🇦 (@micoolpaul) reported

    Hey @O2. Would be handy if you could report a fault on your website. Every postcode in the area just says your network can get busy. When I’m trying to report no internet. Most of East Devon keeps breaking as you fail to resolve any DNS requests, IP based traffic works though.

  • jgbgt jon g (@jgbgt) reported

    @O2 why can you not comply with requirement to send a text- have messaged PAC several times with no reply. Also no reply to INFO. @Ofcom - I’m within cooling off and unable to leave just transferred between departs and PAC text doesn’t work. Please help.

  • Barbara82580398 Barbara Mooney (@Barbara82580398) reported

    @O2 my voucher for a sausage roll said it had been used but I never used it yet

  • Srennie1877 stuart 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@Srennie1877) reported

    @GavNewlandsSNP @O2 The signal in Hampden is awful, it’s the same at st Mirren park so probably just the grounds rather than phone signals

  • stefanpoole87 Stefan Poole (@stefanpoole87) reported

    Great work @O2 Cut my wife’s phone off when renewing contract. Has taken 3 hours to try and get reconnected and then you hung up on her and you are now closed. Now 33 weeks pregnant lady is now without a phone with network.

  • PokerDaz9 Daren Taylor (@PokerDaz9) reported from Radipole, England

    The @O2 network has to be the worst ever. Even with a strong 4G signal, you still can’t get any data use!!! Certainly over subscribed. #notfitforpurpose #OFCOM
