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

  • ThisIsDanGuy Dan Guy (@ThisIsDanGuy) reported from Cardiff, Wales

    @O2 sucks that reduced the number of cafe Nero codes 😡

  • 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.

  • gavinlew Gavin Lewandowski (@gavinlew) reported from Butetown Community, Wales

    @ee need to kick a few cells around the Cardiff arena tonight very poor 4g coverage had to switch to your neighbours at @o2 for connectivity

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

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

  • 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 😔

  • 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.

  • 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

  • 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’

  • 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

  • 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! 🤬

  • 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

  • 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.

  • 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

  • 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

  • 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

  • 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 🤯

  • 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

  • djcue1986 Robert (@djcue1986) reported

    @O2 Every Friday is Black Friday when your an o2 customer - because there’s no signal for my phone to get lit up by anyone

  • chriswb Chris (@chriswb) reported

    So, the merger of @virginmedia and @O2 has increased the price for the customer. Trying renew a contract and VM says I must take a £25 O2 SIM even if I don’t want it!

  • DowlerLorraine Lorraine Dowler (@DowlerLorraine) reported

    @O2 I couldn't make phone calls for around 4-5 hours thursday, this service is getting worse.

  • CoffeeandADHD Jess 🧟‍♀️🧛🏻‍♀️ (@CoffeeandADHD) reported

    People on @O2 check your bills, found Disney+ extra was activated on both contracts even tho we never selected to have them cuz we already had Disney+

  • shearn1986 Shawn Hearn (@shearn1986) reported

    Quite sad that you contact @O2 about network issues and how it doesn’t reflect their coverage map at all and their answer is simply “tough” all of our #Bracknell masts are all out of service indefinitely for upgrades that may or may not be happening.

  • BelleDeMonCoeur Annabel Finley-Kense (@BelleDeMonCoeur) reported

    @O2 What on earth have you done to the signal in AL4 0XH? My phone cuts off all the time. Calls not being received. What is the point of my very expensive contract?

  • spinningthedisc MrDeeJay (@spinningthedisc) reported from Erskine, Scotland

    @o2 doing some testing as I’m looking at joining your network. In the postcode PA1 2AB - 4G signal but no data through put to network. Can you check this issue and if there is a resolution?

  • lil_angi Angie (@lil_angi) reported

    @O2 So, I've only lost total service on my PAYG sim. It's now been 24 hours. My PM monthly is still using the new number.

  • Gobberz Keiron Hopkins (@Gobberz) reported

    @O2 Yes, looks like a mast issue, got less than half a mile away and everything worked again

  • GoaterBilly Billy Goater (@GoaterBilly) reported from Strines, England

    @O2 disappointing that o2 treat us like **** after 20 years as both a personal and business customer. Seems they’re happy for us to walk away. Clueless customer service. No attempt to help us.
