    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! 🤬

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

    @Annabanana8008 @virginmedia @O2 Good luck to you and don't take any sh*t, you should be fully compensated for the absolute inconvenience. We had a little problem with our provider and they where excellent, understood the issue and before we asked they compensated us.

    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

  • 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.

  • 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.

  • 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.

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

    @O2 your live chat service is garbage. 15

    @JoeSims10 @O2 Look forward to no signal on the Portway Joe 🙃

  • AdamLee2011 Adam Lee (@AdamLee2011) reported from Newport, Wales

    @O2 Already with o2 for my mobile and they are brilliant. This was for MiFi, someone recommended three but the signal is terrible. Waste of money.

  • fgethearies FGE ⚡️ (@fgethearies) reported from Cardiff, Wales

    Anyone else on @O2 ? My signal keeps cutting in and out 😩

  • Hayeley Hayley (@Hayeley) reported from Cwmbran Central, Wales

    @O2 is there an option to setup a direct debit without making a phone call? It used to be set up but for some reason didn't change when I used the Switch service to move banks and I'm fed up of being told I'm behind on a payment. Can I do it via the app? Thanks

  • clareoj Clare Osborne Jones (@clareoj) reported from Cardiff, Wales

    @O2 still waiting for a refund on a returned phone case since July...numerous phone calls resulting in last one on 11/10 we will take it off your phone bill for you but full amount taken today. Can’t get through on phones can you please advise as I’m pretty fed up with service

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

    @SkyHelpTeam @O2 why is the network signal so poor/non existant in Cwmbran NP44

  • paigebuckingham Paige🧚🏻‍♀️🌸 (@paigebuckingham) reported from Cardiff, Wales

    Anyone else on @O2 and get literally no signal? I’ve had my baby’s doctor and hospital ring me many occasions and can’t get through to me!

  • 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 😔

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

    @O2 guys is there a backlog in complaints? I responded to a complaint on the 06/10/20 no reply, 20/11/20 no reply. I’ve now sent a further email today and I’ve no faith in it being responded to. Original complaint was 04/09/20.

  • 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

  • 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

  • catlady_cez Cez 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@catlady_cez) reported from Cardiff, Wales

    @O2 Hi I'm just curious, is there a technical problem? I can't get on to the website or the app.

  • _jamieis88 Jamie. (@_jamieis88) reported

    I have never had such bad customer care as I have experienced over the years with @O2 absolutely abhorrent service and I can't think of anything worse than the fact I have years left on the devices on the family plan. 🤬🤬

  • Sentfromdevon1 Sentfromdevon (@Sentfromdevon1) reported

    @O2 again I am having a problem with internet in Nottingham NG2 area. Is there a problem?

  • mcainey88 McAiney Ⓜ️ (@mcainey88) reported from Preston, England

    @O2 no signal or Internet here in preston. Is service down?

  • ZephSib Zeph (@ZephSib) reported

    @O2 trying to make an additional payment for your device, is literally the most frustrating thing you can do on O2..... 5 days later I give up after being told by an customer agent that they I have made 8 payments in the last 8 months doesn't exist 🤔☹

  • NSmith2610 Nigel Smith (@NSmith2610) reported

    @O2 I have spent a week in the Somerset area and have considered moving to the area. If I do, unless I want to cut myself off, I will have change networks. No phone signal and network coverage, extremely intermittent. My companions on other networks, do not seem to have issues!

  • JCyberSec_ Jake | JCyberSec_ (@JCyberSec_) reported

    @ljhew86 @O2 Don't use static domain blocks. This is too slow. You need to create a rule to detect this traffic dynamically based on patterns and other fingerprints Dynamic analysis is how you should block Static block lists have a place but not against these fast flux threats.

  • GorillaoJustice James Humphries GOJ 🦍 (@GorillaoJustice) reported

    Can anyone tell me why my @O2 signal is woeful In Oxfordshire, drops out, often only 3G? I’ve checked the signal websites no clear answer is it upgrading of Masts or something else? It used to be amazing everywhere I went.

  • ac_web_designer Andrew Courtney (@ac_web_designer) reported

    @O2 No the promotion isn't showing on My O2 & the Live Chat team said it didn't apply. It's advertised in the checkout for an Upgrade & New Customer. We confirmed it would apply with local O2 store. Rather not wait for the first bill as this would then be outside the returns period.

  • JMarie_Nx Jordan x (@JMarie_Nx) reported

    @O2 why can’t I make calls and I have no signal?!
