  • 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!

  • 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!

  • 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.

  • 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

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

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

    @westspice @O2 Awful service for me today!

  • 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.

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

    Upgraded my phone last night on the O2 app and already had a notification saying my phone will be delivered to my house address today. Great service well impressed 👍 @O2

  • Asgardpaul Paul Linnane (@Asgardpaul) reported

    @O2 makes me laugh, trying to find out when the latest op system comes out for x3 pro. Oppo says it should be released, waiting for network to approve it. O2 says that it's oppo fault

  • Wavyhill Mr. Write (@Wavyhill) reported

    @O2 My contract has been live for a week now, and you still haven't ported my number. And I've already been charged; no delay THERE. Your chat and phone lines are permanently busy. So let's get this sorted today, or cancel my contract. Hardly an auspicious start.

  • thisisjenks David Jenkins (@thisisjenks) reported

    @O2 - can you help me please? I’m not with you but you keep sending me invoices and bills!

  • knobalob Sophie A 👸🏼 (@knobalob) reported from Spalding, England

    @jammiejam93 @O2 I’ll have to pay. They did that with my other one. I then got a letter saying I had however many days to pay. I’m like for real? I literally rang up wanting to pay there and then, and it was then that ****** me about. Idiots. Absolutely terrible service.

  • thewhicha Chris Whichem (@thewhicha) reported

    @O2 Hello, I currently have o2 pay and go. How do I go about cancelling my account or request for it to@be deleted as I want to move to a different network? Thanks.

  • georgiegirl75 Georgina Johnson (@georgiegirl75) reported

    @O2 sort out your customer service! On hold to sort out a problem that I was told multiple times was dealt with last month! Because I am making a complaint I told the call handler in the payment team that I am recording the call he hung up!

  • LouiseC02346675 Louise Connell (@LouiseC02346675) reported

    @O2 You get over £100/ month from me!! I should be able to get reliable service! Can you at least tell me when this is going to be fixed?? I can’t very well stay in my bone with no tv or internet
