  • PattersonLela1 Lela Patterson (@PattersonLela1) reported from Barry, Wales

    @O2 I didn’t receive an alert and neither did my family. It’s a fantastic idea, though! Are all Network operators doing this? :)

  • 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?

  • acdavies67 anthony davies 🇾🇪🔰🏴󠁧󠁢󠁷󠁬󠁳󠁿🇺🇦 (@acdavies67) reported from Barry, Wales

    Well I've gotta be honest,never again will I take another phone contract out with @O2,wherever I go in a 50 mile radius of my home,my signal is **** and they called me last week offering me more data,more data ?,*******, i can't get anywhere near my data limit now ffs 😡😡😡😡

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

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

  • 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...

  • 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? :-(

  • 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

  • themarkhawkins Mark Hawkins (@themarkhawkins) reported from Barry, Wales

    @viv_wilson @O2 I am in CF62 area, I haven't been able to get more than one bar for years, forget 3/4g Only keep it as I get a good signal in work.

  • 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

  • PattersonLela1 Lela Patterson (@PattersonLela1) reported from Barry, Wales

    Hi @O2. If you received a notification that a sound was played from my phone, please don’t worry. I was just testing out the Find My app on my iPhone, as I’ve never used it before, so I just wanted to check it out and see how it worked. Thank you and sorry. :)

  • 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

    (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.

  • 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!

  • 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

  • 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.... 🙄

  • 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

  • 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?

  • 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

    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" 🙄😡

    @O2 having trouble with access my O2

  • LveLuvLeo Leona Bundy (@LveLuvLeo) reported

    @O2 I’ve already done this and it says the network is down in my area but it’s been saying that forever, even when it was working again. Can someone please look into this and tell me if there is a problem! @O2

  • jadeeyroberts Jade Louise✨ (@jadeeyroberts) reported

    @O2 can someone help me

  • beardedian Ian Roberts - The Beard (@beardedian) reported

    @O2 Turns out your bill was set up right, but the over charge by @virginmedia on their part of the contract has now made me cancel the O2 one after advice from VM on WhatsApp. Looks like that has now cost me the Volt benefits on the account.

  • suelfox Susan (@suelfox) reported

    @O2 code not showing for o Neil’s help

  • morahman1971 Ronnie Rahman (@morahman1971) reported

    @O2 Message for O2 Operations Director in the U.K. Absolutely appalling how O2 completely disconnects you from the Network in the middle of a Child Abduction case. Showing no duty of care towards the customer, disgusting!

  • RosieeRei Rose (@RosieeRei) reported

    @O2 welp. Sucks to be me then I guess.

  • harvardjames James Harvard (@harvardjames) reported

    Hello, @O2, how is it that when my phone falls back to 3G the data connection is SO slow, even with three or four bars reception? Not merely ‘not 4G’ slow, but glacially ‘web pages barely load’ slow. Do your masts just give all their backend bandwidth to 4G connections now?
