  • 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

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

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

  • 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

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

  • 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 👍🏻

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

    @O2 guys is there a backlog in complaints? I responded to a complaint on the 06/10/20 no reply, 20/11/20 no reply. I’ve now sent a further email today and I’ve no faith in it being responded to. Original complaint was 04/09/20.

    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

  • Garethbird85 gareth bird (@Garethbird85) reported from Newport, Wales

    @O2 can someone from customer service contact me please

  • Hayeley Hayley (@Hayeley) reported from Cwmbran Central, Wales

    @O2 is there an option to setup a direct debit without making a phone call? It used to be set up but for some reason didn't change when I used the Switch service to move banks and I'm fed up of being told I'm behind on a payment. Can I do it via the app? Thanks

  • 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?

    @virginmedia @O2 Why is your Hotspot so poor? Never connects!

  • 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 🥳

  • 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!!

  • 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.

  • 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?

  • 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 !!!!!!!!!!!!!

  • 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

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

    What is the point of complaining to @o2? Complaint sent 06/09 multiple times chased up formally 20/11 no reply now 06/0/21. Told someone looking at as a priority still nothing @MarkEvansO2

  • 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...

  • samoakley88 Sam UK Sixers fan Oakley (@samoakley88) reported

    @O2 really ****** up. Said I want to leave or have a better deal after the price increase. Got a legit deal but my eSIM is disconnected and now have no signal. Relying on WiFi on England match day. Fantastic stuff !! #O2

  • SteveLyall1 Steve Lyall (@SteveLyall1) reported

    @O2 Without doubt the worst network you could join. Signal is a joke, you’ll be lucky to ever keep a phone call live. Then there’s the untrained foreign call centres that have no idea what they are doing. If you want to just raise your blood pressure, this is the company for you
