  • 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? :-(

  • 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.... 🙄

  • 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

    (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

    (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

  • 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" 🙄😡

  • 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!

  • 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.

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

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

  • 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

  • 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

  • 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

    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

    (1/3) 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...

  • 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?

  • 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

  • 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?

  • 1Debora Debora (@1Debora) reported

    @O2 I have redeemed my vue code but wasn’t able not able to choose tickets (I was confused because they wanted me to set up a corporate account) and I came out of the app before I’d booked tickets. Now I can’t see how to book using the reward. Please help!

    @O2 @LewisCapaldi Get better coverage & better customer service please. Use these resources to improve coverage first. Basics.

    @O2 @LewisCapaldi Rather than this ridiculous celebrity gumf , please can you improve your network instead as it's pretty terrible!

  • Est19Bay Billy McFad (@Est19Bay) reported

    @O2AcademyGla Who is the local MP to this venue? @o2 do you know what that kneecap chanted? Do you think this is right and they be allowed to chant that in O2 arenas? Will never step foot in there again Utter Disgrace

  • shintyconvert Big Blue (@shintyconvert) reported

    @O2 I’ve never been able to use the £2 Greggs voucher as their system doesn’t recognise it.

  • lundy_graeme graeme lundy (@lundy_graeme) reported

    @O2 @DebbieAinswort2 Yes you are aware of network issues spent 1hr & 15mins explaining to cust services team uninterested in any help or support for disabled and vulnerable customers a disgraceful service

  • FreddiesFather FreddiesFather (@FreddiesFather) reported

    @O2 Why every month do you manage to make topping up grief. The other month received 2 txtx stating top-up payment had not gone through. Guess what payment taken 3 times. Now your doing the same with my sons phone. Abysmal service trying to get more money out of people.

  • chongk42 Kieran Chong (@chongk42) reported
