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

  • 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...

  • 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

  • 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

  • STJonesx S T Jones (@STJonesx) reported from Alway, Wales

    When you’ve not been able to make any calls or texts whilst at home for the last 2 weeks as your phone is constantly on no service! 😡😡 take your time resolving this issue @O2 !!!!!!!!!!!!!

  • STJonesx S T Jones (@STJonesx) reported from Alway, Wales

    Hi @O2 as you’re aware I’ve been on no service now for over 3 weeks, any updates yet or? Or do I just continue to pay £60 a month for a phone I can’t use unless I leave my house ?? If someone with a brain cell can get in contact that would be fab 👍🏻

  • STJonesx S T Jones (@STJonesx) reported from Alway, Wales

    3rd week of no signal and @O2 in absolute NO rush to fix the issue. Can’t wait to cancel my contract this week 🥳

  • 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

  • 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?

  • 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...

  • ImogensMind 👑Immy👑 (@ImogensMind) reported from Blackwood, Wales

    @O2 my friends phone network has completely gone down all day, they can’t call anyone including yourselves. Please suggest what they should do?

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

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

  • 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

  • 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

    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

  • 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...

  • BristolOli Bristol Oli (@BristolOli) reported from Cardiff, Wales

    @BS3Rob @O2 Glad it wasn’t just me - No signal anywhere near the ground

  • 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!

  • GregPaul10 Greg Paul (@GregPaul10) reported

    @the_pieface @O2 is rubbish in a busy area. Football match for example, can’t use anything on it. Very poor. My work phone is @VodafoneUK and never had an issue there!

  • euphrosene Euphrosene Labon aka Wise El (@euphrosene) reported

    @O2 used to be a great service. Now all I get is an annoying sales bot. I cannot top up. I cannot log in. Code sent to my phone but told my phone is not associated with this account! Hanging on for 'sales adviser' but they knock off at 9. I am wilting.

  • Furbz_85 Adam (@Furbz_85) reported

    Found a place where signal for @O2 sucks. Blackpool. 2021 and can't even get 4G to work here.

  • SameerP80638234 Sameer Pawar (@SameerP80638234) reported

    @O2 If I buy O2 refresh monthly plan with device plan and cancel only monthly plan, do I need to give 30 days notice even if I cancel within first 14 days? Device was paid off fully.

  • SimoneLMartin Simone (@SimoneLMartin) reported

    Hi @O2 i’m trying to redeem the £20 off half term activities code on Priority for the Virgin Activity Days but when I try and checkout it’s telling me the code has already been used. Can you help?👀

  • mrandrewdickson Andrew Dickson (@mrandrewdickson) reported

    I should add it's often not in the centre of London that I lose reception, so no big concrete buildings getting in the way. Sounds like a capacity issue so if @O2 could maybe look at ways of improving their service on that front please that would be great!

  • UKWasimPerviz Wasim Perviz (@UKWasimPerviz) reported from Coventry, England

    @O2 can I move from my current network to 02 and keep the same number? Also please follow me

  • rebeccamoule_ becks (@rebeccamoule_) reported
