    @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

  • 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.

  • callumcrowley Callum Crowley (@callumcrowley) reported from Liswerry, Wales

    @O2 customer service are an absolute joke - can’t wait to change my provider #pathetic

  • 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.

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

    @O2 your live chat service is garbage. 15

  • 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

  • StephenADwyer The Dwyer Identify (F) (@StephenADwyer) reported from Caerleon, Wales

    @O2 No signal for two , now on the third day , all your help lines etc are busy , no support or help , not the best customer service but you will still take my money , not impressed at all

  • 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.

  • 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 🤯

  • 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

  • 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! 🤬

  • jamcole88 🇬🇧Jamie🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@jamcole88) reported from Panteg, Wales

    Currently with @EE with no/very low signal at home address! Who wants to send me sim cards so I can see what network to change to! @O2 @o2 @ThreeUKSupport @VodafoneUK @ThreeUK

  • 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.

  • 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

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

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

  • 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

  • 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’

  • callumcrowley Callum Crowley (@callumcrowley) reported from Liswerry, Wales

    @O2 customer service is the worst - transferring me to the sales team knowing they’re closed to fix an error that’s theirs. Can’t wait to change providers - pathetic

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

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

  • 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

    has anyone ever called a helpline that wasn't "experiencing a higher volume of calls than normal" or is that just bull ****? @HMRCcustomers @O2 @ScottishPower

  • Bobbyfagan1985 Bobby Im The Problem Fagan (@Bobbyfagan1985) reported

    On my arse here & @O2 decided put phone bill up 13%, inflation gone down, contract up soon so will not be renewing with u greedy bastard

  • Otapanakara Dani Kaja (@Otapanakara) reported

    Hello @O2, I sent the request to migrate to you and attached the PAC code at the same time I registered, but I received my SIM and it is not my old mobile number. How can I now get my old mobile number with your SIM/Network? I already started a DM to see how can we progress

  • jasont79 jason thompson (@jasont79) reported

    @O2 1 hr and 30 minutes on the phone to your credit reference team gave up great way to treat a loyal customer

  • BessiebUk BessieB.UK (@BessiebUk) reported

    @virginmedia @TheBHF @O2 You sent a letter to me asking me to contact you about a hub change - an hour in and the line goes dead! Your CS is absolutely terrible 😢

  • JonKirby1974 Jon Kirby (@JonKirby1974) reported

    Hey @O2 I thought we be together a while. But if you're gonna have my pants down by hiking my bill up £7 a month by adding 13% inflation + 4% for shits n giggles then alas I'll be off when my contract ends. I'd love to have a 13% payrise..... corporates are ***************

  • MarkBac98827479 COYW (@MarkBac98827479) reported

    @O2 what the hell has happened to your customer service? At any time of day now, your live chat isn’t active and your phone lines have a minimum of 40 minutes wait. 20 years I’ve been an o2 customer for. Not any more, I’m off.

  • richdstew Rich Stewart 🔰 (@richdstew) reported

    Has @O2 gone down?

  • TheTanukiLuke Grappling with Games (@TheTanukiLuke) reported

    @O2 17.3% increase? After the first few months with you as my provider my signal went down to 1 bar and has consistently stayed there. At this point you should be paying me. I know you'll ask me to DM but I've went through it before and went through support on the site and via

  • WezG Wez G (@WezG) reported

    Completely takes the mick that @O2 are increasing their airtime bills by 13.5% in April and also don’t accept customer emails or allow anywhere on website or app to set up direct debit- only option to phone them and I’m stuck in a 45 minute queue - joke #mobilephone network
