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

  • 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!

  • 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? :)

  • 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

  • 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

  • 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

    (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...

  • 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

  • JaeyKelly Jay Kelly (@JaeyKelly) reported from Bridgend, Wales

    @O2 Are there any networks issues in South Wales? For the past week or so my phone signal reverts to 3G.

  • 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?

  • LisaEdwards78 LisaEdwards78 (@LisaEdwards78) reported from Barry, Wales

    @O2 Hi there I have had a highly Sophisticated national insurance scam call from a number registered to your network. There was an automated message purporting to be from the national crime agency. Please can you investigate this number 07850058296

  • 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.

  • 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

  • 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!!

  • 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...

  • 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

  • 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. :)

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

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

  • 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.

  • MigryM migry_main (@MigryM) reported

    Hello? Is the @o2 website broken? I wanted to use chat. I can log in but get a message "somethings gone wrong". The search web page is corrupted an unuable. This was #Chrome . So I tried #FireFox . Same result.

  • SA_Sharman Sarah Sharman (@SA_Sharman) reported

    @O2 @BevMills I don't want to view documents on my phone. Why is the website not working, it's a viscous circle logging in.

  • martin_youldon Martin Youldon (@martin_youldon) reported

    @O2 just come off the phone from your customer service/payments team & I have to say they were fantastic. Really helpful, nothing too much trouble & sorted my issue straight away. The operator was a total credit to his team & O2.

  • BevMills Beverley O'Hearns (@BevMills) reported

    @O2 I’m literally counting down the days when my contract is up and I no longer have to be an o2 customer!

  • fraugretel Sarah Forrester (@fraugretel) reported

    @O2 It doesn’t matter what time of the day or where I am .. the “ offer” is ALWAYS sold out or no longer available!! Never had this issue with Cafe Nero

  • Narmadha Narmada Thiranagama (@Narmadha) reported

    Finally managed to figure out my @o2 payment problems - solution was to download the app and pay by PayPal and not card. I also set up a new direct debit. O2 finally allowed me to access customer services once I’d paid my bill and I spoke to a helpful rep in India.

  • EDIMOYA906 Ayomide Isreal (@EDIMOYA906) reported

    @O2 I never even opened the sim since it was brought by the post mail neither did O2 notify me or text me . After six months they are saying am owing a debt of 658 💷 Looking like l got a subscription scam.

  • MrsDaveGahan Julie Ball (@MrsDaveGahan) reported

    @O2 Since we got it. It has always been poor but now much of the time it is nonexistent. I have moved providers already. I am disappointed that despite the fact the service is so poor, I am still expected to pay to get out of contract. I hope the new provider looks after us better

  • R_jennings2000 Richard Jennings (@R_jennings2000) reported

    @O2 just tried to claim the O2 priority reward for a breakfast roll in greggs however after trying 4 stores not one has any omelette (vegetarian) - not an O2 issue but it’s poor to offer one per group as unable to claim the vegetarian sausage roll instead.

  • abridge__ A Bridge to Tranquility (@abridge__) reported

    Twitter Rant @O2 Me "I've been having signal issues at my home address & within 3 miles meaning unless I use WiFi, I have already contacted you about this issue" @O2 "sorry, have you tried changing etc.." Me " yes I've already have attempted these as stated above" (1/2)
