  • 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.

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

    @O2 How did this shit happen

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

    @westspice @O2 Awful service for me today!

  • 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

  • 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.

  • 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

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 #o2guru said they are doing a network investigation for me. It makes no sense to use 1GB of data in 53 minutes whilst at the theatre. I’d have to be live streaming for that to happen! #o2 @TheO2 #1gbdata #goinggone

  • 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!

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

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

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

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

  • 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!

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 I tried. I think you guys list connection. The guru went to check and never came back!!! 🙈😩 @o2 #o2guru

  • 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

  • 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

  • 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,

  • 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!

  • jesmedlycott Jason Medlycott (@jesmedlycott) reported

    hi @O2 i emailed a complaint about your so called customer service on the 28/09/25 and i have yet to receive any form of reply, or acknowledgment about the whole situation. not surprised considering how you guys delat with it in the 1dt place.

  • PhilBond Phil Bond (@PhilBond) reported

    @O2 customer service on the chat is shocking can’t speak to a person because it’s closed but opening hours are 8-10 what the actual! Quick enough to take customers money but not enough to actually help

  • zrkminterz chloe (@zrkminterz) reported

    @o2 please answer me i need the issue sorted by tomorrow morning xx

  • ss112233445561 Sharjeel shah (@ss112233445561) reported

    @O2 I have been trying to get a proof of Usage and proof of Barring from you for a phone i have used on your network for over a week. I have spoken to multiple agents and have spent over 9 hours on hold. I have had multiple false promises.

  • Elf0207 Emma Williams (@Elf0207) reported from Rawmarsh, England

    How do i complain to 02 because there after service is horrendous. Put a new sim in weeks ago and not had data since and keep getting fobbed off everytime i ring. @O2

  • xAnisaBabyx Anisa (@xAnisaBabyx) reported

    @O2 I’ve been a loyal customer for years, but your service recently has been shocking. I upgraded & ordered 2 phones on 12th & 13th Sept. On 22nd Sept, your loyalty team cancelled my orders without my consent, promised next-day delivery, and never called back. Now I’m told it’ll take another 4 weeks — I needed the phone for my holiday on Tuesday. Weeks of misinformation & broken promises. I want this escalated immediately or I will be leaving O2. @O2 @O2PriorityUK

  • Dcarden2 Dean carden (@Dcarden2) reported

    @O2 no matter what payment I use it’s saying error, I have contacted credit supplier and being told it’s a problem your end

  • ss112233445561 Sharjeel shah (@ss112233445561) reported

    @O2 I have now been told as I did not purchase the phone from you you are unable to offer me my proof of barring and usage and you cannot see it on your network even though it has been in use on o2 since January. I have provided the imei number and proof of purchase.

  • thewildsnappero Josh (@thewildsnappero) reported

    @O2 Is there any reason that you offer gifts (Samsung earbuds for a heavy discount) and then fail to send the code. Go to a store told they cant help and to call customer services, call customer services but their English isn't good enough and 'they dont know what im on about'

  • MarQusRomelle MarQus Romelle (@MarQusRomelle) reported

    @O2 hi guys. Since the app merger with virgin media I’m unable to login via the o2 app without going through account recovery. Will this be fixed or can you help at all? Many thanks.
