  • stourdave Dave (@stourdave) reported from Tottenham, England

    @O2 Yes #stop please **** off with this shit. I only accidentally liked your ad while I was scrolling and you've bombarded me ever since. Your signal is shit anyway.

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @thebrownvixen @O2 It’s the worst

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

    Its amazing @O2 can sort out fraud against my 13 year old daughter but @VodafoneUK cant & tell me to go to my local shop with my daughter to prove she didnt take out a contract like wtf!

  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    @LuzDLuna @O2 When I got to the shop to collect the phone and was denied, since a driving license valid across Europe wasn't good enough, I was told the "there are procedures and cameras" and the staff couldn't help because they would get in trouble!

  • stourdave Dave (@stourdave) reported from London Colney, England

    @O2 How did this shit happen

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • bks67 bridget sparks (@bks67) reported from Hertfordshire, England

    @O2 I do have the app, I think I will phone the customer service team and ask them,

  • AshleyLlewellyn Ashley (@AshleyLlewellyn) reported from Barnet, England

    I have before, but I keep getting told there is no issue with the mast. Or use WiFi, or get a new sim. I just want to be able to use my phone, thinking about ditching you guys and going to @O2 might get a signal and a betting offer on s phone.

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    Dear @O2, I've been with you for years. Just upgraded for 3 years. But the fact that I can't take my phone because my European driving license is not acceptable ID is very annoying. It has my photo and name on it. My passport has the same photo! I really don't see the problem.

  • smileyyearwood Send News!☝🏾🇧🇧 #StopTheCoup 🌹 (@smileyyearwood) reported from Harrow Weald, England

    I've decided to hang onto my @HuaweiMobileUK P30 Pro until the next gen of 5g phones. Was going to take an @O2 deal but it only shows 4g and says you'll then need to take a new chip and contract for 5G not guaranteed you'll pay the same price. A lot of 1st adopters are screwed.

  • aktyrrell Andy Tyrrell (@aktyrrell) reported from Walthamstow, England

    @harwood_steve @O2 @EE EE service is shit around Chingford guys I work with never get a service I'm o2 never had a problem. Probably the country you're in. Plus we always get upgraded at the o2 by the o2 Angel's.

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @Armaanilyas2 @O2 It’s so crap!

  • DimitthriV Dimitthri Vithanage (@DimitthriV) reported from London Colney, England

    @O2 what is going on! 😭😭 Even when I have signal it's so slow!

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

    @AlexCachia5 @laurensc0tt @O2 I've no idea how I managed to get access on there, I gave up trying on o2's priority website and app. I just clicked the date I wanted to book and it worked. Sorry that's not much help for you though.

  • RossGS1892 Ross GS (@RossGS1892) reported

    @O2 app as been down most of the day, lets be thankful that the bots have managed to get some though and are reselling them for £1000, well done @O2 how in ******** did you manage to mess this up in 2020? Both my contracts will be cancelled because of this, jokers #peterkay

  • kerryburkes Kerry Burkes (@kerryburkes) reported

    @O2 It’s been 6 hours since they went on sale and I still can’t get on, that’s an absolute joke O2. You’ll be saying keep trying on Saturday morning when pre-sale ends at this rate. Sort it out and at least give us updates on availability and what you’re doing to fix the app.

  • kenseywhitmorex Kensey (@kenseywhitmorex) reported

    @O2 I don’t understand how the website can still be down!!!!!!

  • H0rr0r1c0n Andy (@H0rr0r1c0n) reported

    @laurensc0tt @O2 Awful service isn’t it! Not even a update saying when it’s gonna be up and running again

  • CupcakeBlaker Linda Blaker (@CupcakeBlaker) reported

    @TheO2 @O2 please hurry up and fix the priority ticket site. Been trying all day to access so I can get tickets for @peterkay_co_uk. Have a feeling I’m going to end up disappointed #severefrustration #PeterKayLive

  • MJM_Collins Margaret Collins (@MJM_Collins) reported

    @O2 is the app and website still down?

  • AlexCachia5 Alex Cachia (@AlexCachia5) reported
