  • 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!

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • AndrewTRIrwin Andrew Irwin (@AndrewTRIrwin) reported from London Colney, England

    @EmmaShubrook @O2 Agreed. I have no signal at all

  • 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.

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

    @Armaanilyas2 @O2 It’s so crap!

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

    @thebrownvixen @O2 It’s the worst

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

  • 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.

  • 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.

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

    @O2 How did this shit happen

  • 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.

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

    @KateAlexa_ @O2 IT IS AWFUL

  • 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.

  • 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!

  • 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

    @JayTaylor_93 @O2 I literally get two bars everywhere. It’s so bad. Really disappointed

  • 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,

  • 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.

  • 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!

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @inoobkilervip @craigglawson @O2 @BBCWatchdog @monzo It will if dont pay it soon haha. Will attempt to speak to an @O2 customer adviser tomorrow and pay over the phone and hopefully that will work

  • gilesshaxted Giles Shaxted (@gilesshaxted) reported

    @O2 Lol. Your map says the signal is fine. Or at least it used to. I can't check it right now. But your map is very wrong.

  • King__Guy10 Guy (@King__Guy10) reported

    @O2 recycled my phone in store on Monday for bank credit which I was informed would be there Wednesday however it is still not there. Could someone help?

  • LoriLieber Lo (@LoriLieber) reported

    Hi @O2. My daughter & I are both feeling completely disposable as customers to you. Having been a loyal customer for 17 years and earning Platinum status on my daughters behalf I am now looking to change the account to her name (as she’s 29) and your CS are telling me … 1/2

  • LaurenOutdoors1 Lauren Baker (@LaurenOutdoors1) reported

    @O2 my signal keeps disappearing, "emergency calls only" then comes back for spells. Work phone on o2 also is right next to it and ok. Tried turning on and off. Happened in last hour as receiving calls this morning. Help!

  • Maggiespursfan spurs fan (@Maggiespursfan) reported

    @O2 can you help me with my order?

  • mjhumble1 martin humble (@mjhumble1) reported

  • wong_jim Jimmy Yuen Ho Wong (@wong_jim) reported

    @O2 New customer you are about to lose here. Your order tracking system has been broken since at least 2014 and the first sim card was lost and the second one is late. Can I get the real tracking number please? No, that's not the parcel number.

  • stevegardner73 Steve Gardner (@stevegardner73) reported

    Ordered my new @O2 sim today. Feels good to be finally leaving @VodafoneUK after so many years of poor signal and service. £10 for 20Gb of 5G data #O2 #Vodafone

  • alexbrod Alex B 👩‍🔬🙋‍♀️💪💙 (@alexbrod) reported

    @O2 Where is the web chat? I've spent absolute ages trying to find support. Way to go to alienate your deaf customer!

  • JimR123 Jim (@JimR123) reported

    @O2 After chatting with two separate reps at @O2 and being passed onto their respective managers, finally somebody actually attempted to fix it, but all of them said it can’t be done, so not holding out hope. Took hours of conversations. Will wait and see if it works. Disgusting.
