    @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

    Simon 💉💉💉🐉 (@uncriticalsimon) reported from Newport, Wales

    @jasonmackenzie @O2 OK I once had trouble with EE (not for the mobile service but when I switched to broadband), it got so bad that I decided to go back to Sky. (NB now with TalkTalk, also not great for customer service but OK if nothing goes wrong.)

  • 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.

  • meribelman
    Peter Williams (@meribelman) reported from Penarth, Wales

    @virginmedia I would happily self serve online, via a browser or app, as you incessantly encourage me to do, but when the page says “oops something went wrong, we’re unable to change your package online”, its very frustrating. @O2 will help you soon!

  • BigDogWrestler
    🌈 Champ (@BigDogWrestler) reported from Cwmbran Central, Wales

    @O2 why is my signal often very poor and I mean often and very very poor?

  • tweetkattweet
    Kathryn (@tweetkattweet) reported from Weston-super-Mare, England

    @O2 hi, I’ve been waiting for a SIM card to be delivered for over a week, tried speaking to your support people who wanted the code they’d sent to the phone which I couldn’t give them as I don’t have the phone! So frustrating

  • gareth_thmpsn
    Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    What is the point of complaining to @o2? Complaint sent 06/09 multiple times chased up formally 20/11 no reply now 06/0/21. Told someone looking at as a priority still nothing @MarkEvansO2

  • nopantsuk
    Nick Thorogood (@nopantsuk) reported from Llanharan, Wales

    @O2 my number should be ported to you today that I requested yesterday morning. I’ve had no confirmation texts or emails though and number still on old network. Any ideas?

  • 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

  • ChrisEddy_7

    It’s come to something when you can get 4 bars of 4G signal walking between Benidorm and Albir in Spain but can’t even get 3 bars of 3G signal in Cwmbran South Wales 👀 @o2

  • 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

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

    @O2 Hi there I have had a highly Sophisticated national insurance scam call from a number registered to your network. There was an automated message purporting to be from the national crime agency. Please can you investigate this number 07850058296

  • BigDogWrestler
    Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia I feel for you, if @O2 and @virginmedia do merge, I'm leaving at the earliest opportunity. @virginmedia leave me a little cold and with no confidence as a customer.

  • 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’

  • 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 🤯

    @virginmedia @O2 Why is your Hotspot so poor? Never connects!

    @DiscoEnergy @O2 After 20+ years I'm just considering going to take out a deal elsewhere . Can get a better deal being a new customer .

  • JohnnyFocal
    Jon Thompson (@JohnnyFocal) reported

    Ok - what has @o2 done to fix their mistake of trying to improve my service by cutting me off? Absolutely nothing - ultimately useless

  • leahculleyyy
    leah 🍒 (@leahculleyyy) reported

    @O2 why can i not get cell service anywhere in my house now? i cannot make or receive calls, so what am i paying for?

  • xxxxminniex
    Minnie (@xxxxminniex) reported

    @Christo44671940 @O2 Thank you, O2 did they put a £5 cap on but it still continued to charge lots over this. Not sure how or why but it’s bad because they told her it was her sending picture messages off the WiFi and didn’t tell her it’s a scam. They even have an link to check premium numbers on the bill so I’m almost positive the call handlers knew it wasn’t my mum doing this herself and it says received texts and not ones she had sent!

  • NotSoP3ng
    ShinP3ngy (@NotSoP3ng) reported

    @lloydoh17 @O2 I’ve been with them a very long time and never had issues like I have each month I’m looking at other networks coz the constant price increases and the drop in service it’s not worth it tbh

  • bethdoreyx

    @O2 why is your app so bad

  • MarkJon63305554
    Mark Jones (@MarkJon63305554) reported

    @Breeze_16 @O2 Call o2 on 202. It's a scam, I just called as received couple of emails re this and asking me to sign in.

  • fishboygtfc
    Padge (@fishboygtfc) reported

    @BennyBlanco22 @O2 @Apple Yep, I had a 5g signal but nothing loading up. Spoke to mates and they said the same. Had it for years, don’t know why I tolerated it. Entire villages I visited with work blacked out. So much better with ID/3.

  • SimonRPoulton
    Simon Poulton (@SimonRPoulton) reported

    Absolutely horrendous treatment of my wife by @O2 . This isn’t even a post to get something moving, already raised to the complaints team, and they’re doubling down on trapping her in a new contract while not supplying her the service she ordered. Terrible customer service!

    @LesTwigg @O2 Funny how the sim can receive signal from various masts, yet fails to work on the internet? BBC website loads, but search engines don't. Thanks for the heads up
