  • kdhanz KD Hansford (@kdhanz) reported from Mountain Ash, Wales

    @EE I'm fed up of your network in aberdare. It hasn't worked tidy for months and I have two contracts with you. Please sort it out or I'm leaving to @VodafoneUK or @O2

  • andrewhillandCo andrew hill (@andrewhillandCo) reported from Abercynon, Wales

    @O2 @JohnnyMercerUK bit late that isn’t it - I think he has just a few followers who may have seen this and your ‘standard good customer response’

  • gingio Shane (@gingio) reported from Cardiff, Wales

    @jgfoxy @O2 @ThreeUK Good choice! I love being with 3 and find my signal is much better than that on my work phone which is o2.

  • jamieriddell Jamie Riddell (@jamieriddell) reported from Cardiff, Wales

    Hey @O2 who can I talk to about unlocking a phone. I've paid up and out of contact. Online form says no because of too many attempts ( no idea what my customer service code was) but I have all my account details.

  • ieuanbeal15 Ieuan-Rhys Beal (@ieuanbeal15) reported from Cardiff, Wales

    @O2 your live chat service is garbage. 15

  • HywelButcher Hywel Butcher (@HywelButcher) reported from Cardiff, Wales

    Top tip - don’t join @O2 - incompetent and useless! First no 4G, now no signal or data at all 🤯

  • Statto1927 Simon Hiscocks (@Statto1927) reported from Barry, Wales

    @O2 2/2 it’s like someone deliberately switches off the internet on match days, but I’m sure that doesn’t happpen.....😉 Signal is perfectly fine there usually, & if it’s vol7me of people, why are other able to connect seems like an O2 thing as my son & daughter also have problems..

  • BradChanner Brad Channer (@BradChanner) reported from Cardiff, Wales

    @teamIPSE Without a doubt! And phone signal! It is appalling how bad the signal is in parts of the UK outside of London! I am 4 minutes from the Cardiff city centre with no signal! #howareyoumeanttorunabusiness @o2networks @O2 @giffgaff

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @pinecone95 @O2 It's coming along slowly but surely. No sign in Barry or Cardiff yet.

  • CJLittlemore Callum James Littlemore 🔶 (@CJLittlemore) reported from Cardiff, Wales

    @O2 I woke up this morning to find I’ve been totally cut off. I can’t make calls, send texts or use my mobile data. All of this is kinda important for my work as I’m self employed - I can’t call your customer service line to see what the issue is. Can you look into it please.

  • staceyjhubbard Stacey J Hubbard 🐧 (@staceyjhubbard) reported from Cardiff, Wales

    Also when I highlighted my issues over the phone and through the Webchat @O2 do not seem very concerned or understanding 😔

  • daunce4thstreet Garry Dauncey (@daunce4thstreet) reported from Pontypridd, Wales

    Never use @O2 recycle! sent them a phone that was in perfect condition & now they say the phone is damaged and are offering peanuts for it. If it’s damaged blame the flimsy packaging you send.

  • bethanjane22 Beth (@bethanjane22) reported from Cardiff, Wales

    When I renew, @virginmedia offer free AirPods with some plans and @O2 do the same! So much for customer loyalty, they just want more and more money! 🤬

  • BradChanner Brad Channer (@BradChanner) reported from Cardiff, Wales

    @O2 This has always been an issue. We are with giffgaff whom I believe use your signal. I have tried everything. I have even bought a booster, but the reception coming into the booster isn’t enough to even make the booster work. Very frustrating. I have to sit in a window 4 reception

  • LisardoVivas Lisardo Vivas (@LisardoVivas) reported from Cardiff, Wales

    @O2 @tig1985 I’m in cardiff with same issue

  • pwilliamsevents Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales

    Totally disappointed with @O2 customer service. A number transfer from a consumer account to business took 8 days when I was told it would take 24 hours. 3 phone calls to customer service and still not 100% sorted. #totallycrapexperience

  • Waldron_Diana Diana Waldron (@Waldron_Diana) reported from Cardiff, Wales

    @O2 can u please help. I have been trying to pay my final bill with you for ages. It’s only about £20,I don’t need harrazing letters&emails to prompt me to pay...I just need u to let me pay. I have called&been online to make payment, but you don’t seem to want to take my payment

  • Bubwal Ade (@Bubwal) reported from Cardiff, Wales

    @RobBruceK @ThreeUK @O2 @EE @VodafoneUK No awful. Just spent 5 days with no data/calls due ti Insufficient bandwidth. My family and friends who were with O2/BT/Vodaphone had no problems. Worst ever. So regret leaving previous provider last month. Their coverage checker is inaccurate too

  • pwilliamsevents Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales

    @jolilford @O2 Your kidding me!!! I have contacted customer services 3 or 4 times. Shocking service

  • staceyjhubbard Stacey J Hubbard 🐧 (@staceyjhubbard) reported from Cardiff, Wales

    There is always some kind of problem with my @O2 order. Its even more frustrating seeing on here people have just walked into the store and been able to collect the phone without the relevant email saying its ready to collect. How do they know they are distributing the right

  • SimonAlexanderO Simon Alexander Ong (@SimonAlexanderO) reported

    @O2 All works now. Website didn’t do anything so used the text service

  • sungrad sungrad (@sungrad) reported

    @VodafoneUK hey, been having home broadband issues for a few hours. Disney, Netflix and YouTube all refusing to load, and even your website is taking ages - I've had to drop back to @O2's 4G. What's up?

  • jammie82uk jim (@jammie82uk) reported

    @O2 Hi, just wondering if O2 actually want my business? My port in was supposed to happen today by 6pm after been trying to get it done for a week!!!!! I am currently having to pay for 2 contracts (my old network and O2) due to O2’s incompetence

  • Sarah42242355 Sarah (@Sarah42242355) reported

    @O2 Hi all! I haven't been able to use my phone for a few days now because of work being done on the local mast. Am I going to be still charged for the days that the service is down? X

  • TelefonicaUK Telefónica in the UK (@TelefonicaUK) reported

    Don’t miss out! 🙌 Bubl’s here to help get the nation back on its feet! 🤖 @O2’s new ad focuses on putting customers first, with low offers on the latest tech. 👇

  • Flamingo_code Steph (@Flamingo_code) reported

    @O2 You need to make this clearer though. I was told by customer services anyway that once the number is ported you would have lost any credit. My sim card says the last chance to top up was 19th, received the sim only yesterday.

  • jamesdude11 J (@jamesdude11) reported

    @O2 Hi O2 - does the Moto G8 Power support 4G Calling on O2? Thanks

  • KerrieAHughes Kerrie Hughes (@KerrieAHughes) reported

    @O2 5 phone calls to 5 different people over 3 hours trying to get a resolve to sort out a phone contract, only to be told there's nothing that can be done. Quite possibly the worst customer service I have ever come across. Appalling is an understatement @O2

  • MiBz0r Lee MiB© Exley (@MiBz0r) reported

    @O2 Yes, this problem happens on ALL devices and it isn't just me having it, how about getting it resolved rather than acting nobody knows about it??

  • eeeeebcux cocolatina (@eeeeebcux) reported

    @O2 i spoke to an advisor about upgrading. She was supposed to call me yesterday and didn’t. Do customer service reps take notes so that I can speak to someone else?
