  • 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.

  • Rhian1975 Rhian Langham (@Rhian1975) reported from Cardiff, Wales

    @O2 shocking attitude of customer service rep. Please get in touch.

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

    @O2 your live chat service is garbage. 15

  • 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.

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

    @O2 It’s CF11 8AZ. ardiff City Stadium. My point is that I can hardly get any connectiveity with a 4G signal showing. Someone sat next to me with EE can connect. Granted it’s a sports stadium but this was 60m before kick off with barley anyone in there. Happens every match 1/2

  • 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

  • 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

  • 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.

  • 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! 🤬

  • 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

  • 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

  • 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.

  • 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

  • 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

    @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

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

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

  • 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’

  • 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

    @TomUK199 @EnglandRugby @O2 Yes, never seen him underperform for either Exeter or Sale. Felt it was a real coup when Sale got him

  • rolfe_hayley Hayley Rolfe (@rolfe_hayley) reported

    @O2 so you won't answer any form of communication I need to pay my bill. But I can't do that because I never activated the sim so can't log in to myo2 I'm am not being charged late fees because you won't answer

  • SPECTRUMperspec Ross (@SPECTRUMperspec) reported

    @O2 will you be replacing your #O2Priority @ODEONCinemas free 2D ticket weekly offer? I was devastated to know it’s was the last week, this was the best part of being on O2 and I think I’d change network if you didn’t offer it anymore 😢

  • LynseyRhiannon Lynsey Cuthbertson (@LynseyRhiannon) reported

    @O2 I have been trying to speak to someone to change my payment day for weeks and every single time I get an automated message to say your busy. Currently on hold and have been for 30 minutes. Can never get to speak to anyone.

  • mkevans32 Megan Evans (@mkevans32) reported

    @O2 trying to DM you and it keeps saying message failed. This is now beyond a joke.. Have now decided I just want to cancel my contract never had service like this.

  • DBS050106 David Surtees (@DBS050106) reported

    @O2 paid our last device bill on 28/2. Why are you now saying it’s overdue???? Can’t get through on 202 and your chat is a useful as a fart in a lift!!! Help.

  • adamsn Nj (@adamsn) reported

    @O2 I spent half an hour waiting to speak your customer service team. Then got out back on hold for another 30 mins to be put back through to payment management team only to put back to customer service. It took me a hour and 15 to resolve the issue.

  • R4V11 . (@R4V11) reported

    I take it no one bothers about customer service on here as you know your service has been appalling? @O2 @virginmedia

  • Alex83838395 Alex (@Alex83838395) reported

    How dare @O2 how dare you keep me on hold for 40 mins then hang up on me your advisers are rude and your a robbing company.

  • Ruby_V_Green Ruby Victoria-Green (@Ruby_V_Green) reported

    Dear @O2 why do I never have a signal? I cannot actually ask, as guess what, I have no signal!!
