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

  • 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.

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

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

  • 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.

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

    @O2 your live chat service is garbage. 15

  • 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

  • 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

  • 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! 🤬

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

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

  • 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

  • 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

  • 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.

  • 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 😔

  • 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

  • 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..

  • 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

  • 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

  • AdamSmith0810 Adam (@AdamSmith0810) reported

    @O2 i DM’d you and I have had no reply, this is indeed upsetting to find out this is how you treat your loyal customers. I will be taking my custom somewhere else in future.

  • TheeFariha Farimomo (@TheeFariha) reported

    @O2 my number hasn’t ported over to your network fully. I have moved from Vodafone to O2 and my O2 sim has no signal. I started the process on Sunday night.

  • har17958 Amanda Harbert (@har17958) reported

    @O2 @simonpegg @SimonCowell I am trying to cancel my contract and have wasted hours on the phone to your “customer service” without any success!! Terrible terrible customer service!

  • HannahCox2306 Hannah Cox (@HannahCox2306) reported

    @O2 I need you to sort the service out in York asap! I have no service at all and need to make my son a doctors appointment but can’t make or receive calls due to have no service at all

  • PiggyMalone1 Piggy Malone (@PiggyMalone1) reported

    @O2 Telefonica is a criminal outfit and they do not give a flying f*** about the UK, hence almost zero investment in network coverage over here.

  • DebbieAnne2224 Debbie (@DebbieAnne2224) reported

    @O2 son has phoned snatched and Im desperately trying to put hold on account why he travels home. spoke to someone who won’t help and when I asked if his phone is used for international calls whilst they won’t put a hold on will O2 charge him. She put the phone down !

  • V3r0n1c4_45 Veronica (@V3r0n1c4_45) reported

    @O2 Hi team, my contract is ending 30th April, how can I cancel it and take my number to a different provider? Thanks

  • Rachel_McDerby Rachel McDerby (@Rachel_McDerby) reported

    @O2 trying to top up a PAYG SIM via the automated line to activate as advised by your customer service agent on the phone but it will not go through despite numerous attempts. Is my only option to go in store to get it sorted?

  • BeltinMon Mark North (@BeltinMon) reported

    @O2 I can’t use my phone cause you’ve been down since yesterday you and virgin media playing up what’s going on

  • TraceyPyke3 Tracey Pyke (@TraceyPyke3) reported
