  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

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

    @O2 How did this shit happen

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

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

  • 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!

  • Craigcanfield Craig Canfield (@Craigcanfield) reported from Welwyn Garden City, England

    @O2 contract finished.. put on a rolling month deal.. nothing will change they said... 2 days now with no phone signal.. "sim provisioned"! Customer svc say it'll work soon. Gggrrr

  • 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.

  • 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!

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • 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,

  • WickhamofWare Jonathan Flood (@WickhamofWare) reported from Stevenage District, England

    @O2 @tescomobile No mobile signal in Great Ashby, Stevenage all day!!

  • Steve_Edwards77 Steve Edwards (@Steve_Edwards77) reported from Hertfordshire, England

    @westspice @O2 Awful service for me today!

  • ItsMeEllisxD Ellis Brown (@ItsMeEllisxD) reported from London Colney, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • 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.

  • OmarMansoor Omar Mansoor (@OmarMansoor) reported from London Colney, England

    @Ali_Malik @O2 @Ofcom @MarkEvansO2 I’ll give them a #Valentine chance - never had issues before but now only on crucial days they go down. #

  • Elissa524 Elissa Da Costa (@Elissa524) reported from St Albans, England

    @O2 Not sure what happened but all ok now thanks. Very good service to get me reconnected quickly

  • banafshbanafsh banafsheh (@banafshbanafsh) reported from Waltham Abbey, England

    @TazPDN @O2 So sorry to hear that ,#o2 is really bad, I'm with Vodaphone and they are much much better . Hope all get sorted for you x

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

Latest outage, problems and issue reports in social media:

  • nick_murrell Nick Murrell (@nick_murrell) reported

    @O2 Doesn't answer the question and hiding the speeds away in t&c is poor customer experience. So again, why is it capped at such a low speed it effectively makes smartphone usage impossible? #02

  • AndrewKanter Andrew Kanter (@AndrewKanter) reported

    Hey @O2, switching from 3 after 10 years. Billing started days before my SIM arrived (not yet!). It's only £1.50 but off to a terrible start - this is outright theft. Now 20+ minutes into a chat to try and get resolved.

  • pauljakubowsk11 paul jakubowski (@pauljakubowsk11) reported

    @EnglandRugby @O2 Awful just Awful!

  • Becky_Corber Becky Corber (@Becky_Corber) reported

    @O2 Why can’t I speak to you on 202? Doesn’t ring and cuts off… No problem calling any other number

  • kartik_cs Kartik Chandrasekhar (@kartik_cs) reported

    @O2 Hi, could I please know why I got a reply within 2 minutes of my original and no follow up after that? I want to know how to make a complaint. I spoke to one of your colleagues on Live Chat, but that wasted 30 minutes of my time and I still don’t know what the issue is.

  • toonharveylass Howay maan! (@toonharveylass) reported

    @O2 Hi. I upgraded my sim only in July and part of the offer was a £50 digital giftcard. I reveived an email to register this but had nothing since. 3 other people i know did this upgrade offer aswell and have heard nothing either. Can you help please? Thankyou.

  • Michael_JDean Michael Dean (@Michael_JDean) reported

    Having real trouble getting through on the phone to @O2 😔

  • shivarajsharma_ Shivaraj Sharma (@shivarajsharma_) reported

    One for the worst #network across #UK @ThreeUK false commitments and no proper customer support @EE @O2 please help me

  • FrostyFrosty_ Frosty (@FrostyFrosty_) reported

    @O2 Called and got through to someone. They’ve received no notification that my order will be at the store and then said it’ll be unlikely my phone will be in soon. Absolute shambles of a company. Disgraceful customer service.

  • rsrikigrps Srikant Ravuri (@rsrikigrps) reported

    @O2 One of your customer service deactivated by number when I wanted to take out additional contract and now I am left without a number for the last 5 days. Been calling "202" several times but no help, waiting for a manager's call for the last 4 days. is this level of service?
