    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 👍🏻

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

    @O2 can someone from customer service contact me please

  • 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?

  • 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

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

  • 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

  • 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

  • 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 🥳

  • 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?

  • 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.

  • 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 !!!!!!!!!!!!!

  • 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

  • SamHallWales Sam Hall 🏴󠁧󠁢󠁷󠁬󠁳󠁿🐾🐾🌈 (@SamHallWales) reported from Cwmbran Central, Wales

  • 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...

  • 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

    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

    (1/4) 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...

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

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

  • SimpaticoGem Gemma ≅ (@SimpaticoGem) reported from Walkden, England

    Tell me why with my @virginmedia wifi and my @O2 phone contract, MY WIFI CUTS OUT CONSTANTLY AND I HAVE NO SIGNAL ANYWHERE I GO?! Thought being a customer of you both was supposed to reap massive benefits for me?

  • gazzlynch85 gareth.Lynch (@gazzlynch85) reported

    @O2 very unprofessional and disrespectful company when with very poor customer service dealing with genuine and serious complaints, no matter how loyal you may have been over the last 10/15 years. Broken promises and constantly fobbed off....... 😡😡

  • izz_wizz not so easy davidson 🇺🇦🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺 (@izz_wizz) reported

    . Anyone ever tried to get their phone services resumed by 02? @O2 I have spoken to 5 people; 2 did not reconnect my services & 3 did not call back when they said they would. O2 chat said it was fixed and it wasn’t. Still no service after 3 days. Should I change provider?

  • ladysmanca Simona_la tradulettrice (@ladysmanca) reported from Edinburgh, Scotland

    @O2 Thanks! As I need my phone for work I need to sort the issue soon.

  • ASG19 Ally Gilmour (@ASG19) reported

    @O2 I have arrived in the US for the second time this year. My iphone has no signal At all this time. It’s just saying SOS. I have just updated the software to ios16. Nothing else. Any suggestions to get my signal?

  • LittyMan Paul Lewis (@LittyMan) reported

    @o2. Your service in Central Bath Uk, is appalling. Limited data (4g) at the Bath Rugby match, won't even allow me to tweet about my favorite rugby team. Please don't reply with a 'sorry'. Getting fed up with excuses. Get it sorted instead. #poorcustomerservice #NoExcuses
