  • 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

  • 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

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

    @O2 How did this shit happen

  • 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!

  • 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

  • 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

  • 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

  • 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

  • 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!

  • 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.

  • 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

  • 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. #

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

    @westspice @O2 Awful service for me today!

  • 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

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

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

  • 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!

  • 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.

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

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

  • 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!!

  • larahyearwood Larah Yearwood (@larahyearwood) reported

    @O2 why is there never a good signal or 5G/4G in & around Ashford, Kent?? What exactly am I paying you for?!?

  • Wendy73850246 iam me (@Wendy73850246) reported

    @O2 I have been doing that it doesn’t exactly help the issue of not having any service and needing a phone for work

  • langton301 Steve Langton (@langton301) reported

    I can't believe I've been charged data roaming from Albania, a country I HAVE NEVER BEEN TO!!!! @O2 won't let me talk to anyone about it #O2

  • StompTheBean Stomp (@StompTheBean) reported

    @O2 is your network down ? I've been waiting all day for my number to swap SIM cards and I still have no service on either of my phone's ?

  • mrslisaboyce Lisa Boyce (@mrslisaboyce) reported

    @O2 I can’t even dial out 4444. The phone won’t ring on the handset yet I can hear it ringing on my other handset. I topped up once before the phone went back to the U.K. to get registered on the network.

  • ilkleycaraudio Ilkley Car Audio Ltd (@ilkleycaraudio) reported

    @O2 Thankyou for wrecking my credit report with your inaccurate loading of my credit file. You’ve literally pulled my final straw, you’ve lost me as a customer. 2 iPad Pro contracts 2 apple watches 2 iPhone pro max accounts Your loss

  • julieheat Julie Heathcote (@julieheat) reported

    @HattieCSeaton1 @O2 @sophlmiddleton Yes me too. Upgraded in the store yesterday morning and still can’t make or receive calls 30 hours later. Completely unacceptable service..
