  • 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

  • flowersshanice S H A N I C E (@flowersshanice) reported from Cardiff, Wales

    Hi @O2 I’m in desperate need for someone to active my new sim (had an upgrade) as I’m unable to text or call out viseversa. My o2 isn’t solving the issue either.

  • 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.

  • JdBowns91 Jade Bowns (@JdBowns91) reported from Barry, Wales

    @O2 on the website it says to contact your customer services to change my name and other issues I want to discuss yet the only way I can get through to someone is to say I’ve had fraud occur! All I want to do is speak to someone why is it so hard. Chat is also unavailable

  • TweetterRoss Ross Maisey (@TweetterRoss) reported from Church Village, Wales

    @O2 Struggling with no or little service at home at the moment and it’s becoming very frustrating. I checked the service checker and they comes back as ok. My phone says 1 bar but that doesn’t allow me to use the internet.

  • 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

  • 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

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

  • 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

  • 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.

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

  • BCFCOLIVERDOG Oliver City Dog (@BCFCOLIVERDOG) reported from Cardiff, Wales

  • whirlwind147 Graham Howe (@whirlwind147) reported

    @O2 hi, I sent a DM early this afternoon about a porting issue but not had a response yet. Can someone look at it please? TIA

  • OooPooLooMooZoo Seonaid MacKay (@OooPooLooMooZoo) reported

    @O2 ….If you try a network, discover the reception is terrible and you need to leave, do you not only have to let the network know, but must organise new provider, new sim and transfer your PAC within that 14 days? Or do you have the length of time PAC is valid?

  • jsdevans Stephen Evans (@jsdevans) reported

    @O2 How about just dealing with serious customer complaints @LutzSchueler ? Your shocking and disgraceful

  • madjhatters James Hatfield (@madjhatters) reported

    @O2 I’ve had enough now! Paying a lot of money for a subpar service! Phone says I have 4G yet nothing is loading on mobile data! Been like this for over a year

  • Ronin_Karim Karim Belgacem (@Ronin_Karim) reported

    @O2 Thank you for messaging me this morning and then completely IGNORING my response. So.. let’s tally this up… FIVE failed call backs by management and a message from customer services which was pointless. Keep getting better and better here!

  • becks_sim Becky Sim (@becks_sim) reported

    @O2 your 4G is shockingly bad right now. I can't even use my data to scroll the internet it's that slow. My broadband has been down the past 4 days, so I am having to rely on 4G, but it's impossible. What is going on??

  • FusionMythic16 Robert (@FusionMythic16) reported

    @O2 absolutely disgusted with support. Back and forth with the same thing to go to half an hour on the phone for it to get ended multiple times to now unable till tomorrow.

  • Yvss_World Yvonne (@Yvss_World) reported

    Why is this 5g so damn slow @O2 ???? 😭

  • wendyc1982 Wendy (@wendyc1982) reported from Carnoustie, Scotland

  • jolaurenx JO ♡ (@jolaurenx) reported

    @O2 3) having data and signal when you’re out and about but I can’t relate because I’m on o2 and can’t use my phone unless it’s connected to WiFi yet I’m still paying £140 a month for 2 phones that don’t work.. 🙃🙄
