  • 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?

  • 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 🥳

  • 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" 🙄😡

  • 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

    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

  • 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 !!!!!!!!!!!!!

  • 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!!

  • 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.

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

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

  • 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

  • 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 👍🏻

  • 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

  • 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

  • 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!

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

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