  • SLCC1 Stephen Ludlam (@SLCC1) reported from Killamarsh, England

    Hi @O2 haven't had 3g or 4g on my phone for a few days and can't get Internet on my phone if not connected to WiFi. Are there any issues? I'm in S21

  • LukeA8 Luke (@LukeA8) reported from Barnsley, England

    @O2 Saying there’s now a mast down but it’s useless normally anyway. Terrible.

  • srounce Shane Rounce (@srounce) reported from Sheffield, England

    @O2 It’s an issue for everyone, not just me. Either delist it from your website as it’s obviously not in stock. It still says next day delivery right now. That’s 100% fraud. I demand to deal with it publicly.

  • SLThomas99 Sara Thomas (@SLThomas99) reported from Sheffield, England

    @O2 - 2nd time got through to Customer Services rep Neil Clarke. Excellent service and very informative. A credit to your team and he could certainly have taught the first guy something. Please try to reduce hold times though took me nearly 2 hours in total 😬

  • victimsvoice73 Victims Voice (@victimsvoice73) reported from Sheffield, England

    Anyone recommend a phone network been with @O2 for years and since it merged with @virginmedia it’s shocking. When I went on holiday before I’d never had problems this year wouldn’t let me go my own internet & here signal keeps going for phoning not to mention rise in scam calls

  • theandycooke Andy (@theandycooke) reported from Barnsley, England

    Really glad I managed to leave @O2 and go back to @EE. They said they couldn’t guarantee signal on the 🚂 dropping me down to E like it’s 2005! But I’m here with 5G on EE! #Signal #Connectivity

  • leanneellis Leanne Robinson (@leanneellis) reported from Barlborough, England

    @O2 Five calls to 202. Once after 15 minutes on hold a message asks which number you should send a questionnaire to and then hangs up. Other four times the automated voice randomly says bye half way through the menus. Why is it so hard to speak to support 🤬🤬🤬

  • AnnielizzieSten Annie (@AnnielizzieSten) reported from Sheffield, England

    Hi @O2 I have no complaints about your service but if you advertise on GB News I will immediately change my mobile phone provider #DontFundGBNews

  • srounce Shane Rounce (@srounce) reported from Sheffield, England

    @O2 It’s not in stock for anyone, how about you reply to some other people that DM’ed you over the same issue? The incompetence here is staggering.

  • SLThomas99 Sara Thomas (@SLThomas99) reported from Sheffield, England

    @O2 A very mixed service today. Nearly lost the will to live after being on hold for 27 mins then being put on hold and cut off - your first representative didn't even bother to call us back - do you know how frustrating that is! Another 35 mins on hold and finally got through!

  • srounce Shane Rounce (@srounce) reported from Sheffield, England

    @O2 I’d rather deal with your fraudulent practises publicly. I only just woke up and expect immediate support, given my sleep disorder it would be very bad for you to not accommodate me at this time.

  • atwal_brice Michael Atwal-Brice He/Him (@atwal_brice) reported from Sheffield, England

    @O2 terrible signal in s63 areas is a mask down or something?

  • frakcha Chuck Frakes (@frakcha) reported from Bolsover, England

    Trying to port my number online but keep getting rejection emails - bit of help @O2

  • srounce Shane Rounce (@srounce) reported from Sheffield, England

    @JordKnowles @O2 They aren’t restocking till late January. Confirmed via phone support. Beyond annoyed.

  • GlennJHarris Glenn (@GlennJHarris) reported from Sheffield, England

    @O2 how do I cancel an order that I’ve made

  • barnsleysime Barnsley Sime: DJ. (@barnsleysime) reported from Barnsley, England

    i give up with @O2 online help. all i need to know is, can i buy an apple watch and connect it to my existing simo contract? (using iphone X) all it says is it has to be a "monthly contract". the simo is an 18 month one. HELP!

  • theandycooke Andy (@theandycooke) reported from Barnsley, England

    @O2 On the commute into Sheffield I had issues with signal, at time went to 3G (I can’t remember the last time I saw 3G with @EE). I also had some signal issues whilst at work in the centre of Sheffield & didn’t once achieve a 5G signal.

  • goonie2008 Andrew Lee (@goonie2008) reported from Sheffield, England

    @virginmedia @O2 Its definitely you lot Robin as your broadband service was a disgrace when I moved to you and I had to pay out for cancelling contract early. If this is what’s to come O2 then you will a customer of over 15 years.

  • busymum777 Laura Hughes (@busymum777) reported from Ivybridge, England

    @O2 worst customer service EVER. Do you actually want customers???

  • busymum777 Laura Hughes (@busymum777) reported from Ivybridge, England

    @O2 extraordinary appalling service followed by no replies on here or via direct message. Reporting you to offcom first thing Monday.

  • 1997whovian Lauren Brown 🐧 (@1997whovian) reported

    @O2 ever since you began improving the network in the NE63 areas, my data and also my uncle's has been really slow, despite apparently having 4G. From taking only seconds to download stuff can now take up to 20 plus hours. Therefore you haven't improved it at all

  • davidboyes_ David Boyes (@davidboyes_) reported

    @O2 help please, I’m trying to buy accessories but my student discount code isn’t working on the basket??

  • StuartMallen Stuart Mallen (@StuartMallen) reported

    .@O2 - have ordered an Apple Watch through my02. I have been a customer with you since you were BT Cellnet! finding it difficult for you to deliver this watch - ridiculous. you want me not order it? I have an iphone and iPad with you. Would appreciate it could be delivered.

  • G4CFS Glyn Dodwell CDM (@G4CFS) reported

    Why is @O2 customer service beyond incompetant and unfit for purpose?

  • ciarand78 ciarand78 (@ciarand78) reported

    @O2 dear O2 please please can you but 5g in my area of Isle of Dogs the courage on the network on the island is awful please upgrade it

  • whatshernamexo Chelsea (@whatshernamexo) reported

    @RossKyleJohnson @O2 Try a SIM swap mate. Usually sorts this kinda **** out, just pop into store with ID and they'll sort it

  • kyle_harring Kyle Harring (@kyle_harring) reported

    @YepJustJack @O2 I tried, at least! What did you empathise about? Agaaaaaain, why do you think it’s not relavant to know why someone has a meltdown if it’s so bad the police had to be involved? Not answering and saying ‘you don’t care’ doesn’t really make sense, does it?
