  • AlanGreene73 Alan Greene (@AlanGreene73) reported from Bexleyheath, England

    @O2 It can happen anywhere at any time. Only way I know is when I look at phone. It’s not signal as when I turn phone off then back on it’s got full signal. It’s not just me. Check Twitter feed. So many people complaining about same problem

  • paullferrer Paul Ferrer (@paullferrer) reported from Harrow Weald, England

    @O2 Two weeks later still have low signal and no one is telling me when it will be fixed you pass me to Sky Mobile who say its your masts they use and contact you

  • tjwmurphy Timothy Murphy (@tjwmurphy) reported from Paddington, England

    @virginmedia No error. It just fails to connect. The Tick actually appears in the Wi-fi settingswhich makes it seem that the @o2 advert will pop up (the final step before connecting) but it never does. I have restarted my phone several times.

  • s11kda Sam D (@s11kda) reported from City of London, England

    @jimsmallman @O2 I left them a few years ago because the customer service is god awful! @ThreeUK is the best bet for the amount we travel! Not the best in London but all over the world it’s great

  • spiritualvodka gwen 🕸🕷 (@spiritualvodka) reported from Stratford, England

    @O2 hi! I’m not sure if this is a you problem or an apple problem. But my mobile data will completely shut off around 4/5 times a day, turning the data on and off doesn’t bring it back. I have to completely reboot my phone 5 times a day at the moment. Pls help!!

    @o2 Thanks again to Connor Burns in your Belfast contact centre for his help yesterday with my upgrade, I’ve completed the order for my iPhone 11 Pro this morning 😀

  • lofty_london London Lofty (@lofty_london) reported from Camberwell, England

    @O2 Can you explain what they are please, why the mystery. I pay for a service that doesn't work where I live.

  • ejp72 Liz (@ejp72) reported from Poplar, England

    @O2 It’s always like it. I’ve never had a decent signal here. Could be the buildings maybe. But always like it.

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • onlyslightlybsd Onlyslightlybiased (@onlyslightlybsd) reported

    @O2 Have been waiting on hold for about half an hour now, is there any other way of organising a return? Either in store or through a webchat service

  • Northlander74 𝔖𝔱𝔢𝔭𝔥𝔢𝔫 𝔍. 𝔍𝔞𝔠𝔮𝔲𝔢𝔰 (@Northlander74) reported

    @bt_uk I can assume that any terms of cancellation of my contract are now void because since December I've received no mobile signal while at my workplace location... Seems unfair to me to pay for a non-service. Might as well speak to @VodafoneUK or @O2 to see if I'll receive any signal

  • _drakeO Thomas Drake (@_drakeO) reported

    @O2 (tweet 2 of 2) Constantly being cut off as well. Now totalled to just over 6 hours of calls just to get nowhere. Absolute shambles, am a long standing customer, however now taking business to a rival instead as I have had enough, you do not deserve my money!

  • Jimb0b007007 JimBob (@Jimb0b007007) reported

    Well @giffgaff @O2, having evaluated your service all over the country for use as a backup to my main @EE sim on my dual sim phone. I find your service absolutely abysmal and not even suitable as a backup. Therefore I must dispense with your shocking network.

  • nirave Nirave 尼拉夫 (@nirave) reported

    @Heidivel @VodafoneUK Don’t change to O2 – trust me on that, they’re the worst UK network possible and their customer service is ATROCIOUS. You’ll be waiting a day for a single message in response from @O2 as well.

  • SrockettSam sam (@SrockettSam) reported

    @O2 dreadful customer service, fraud team never contact you I've been waiting 42 days, quick enough to send me 8 debt letters though!! 2 complaints put in told response within 5 days again no one gets back to you. DM tell you how sorry they are they'll esculate it still waiting

  • TheWildStuff jayme (@TheWildStuff) reported

    @O2 I’ve been waiting since December for someone to get back to me on a bill that has been looked into apparently 3 times , I’ve since made a complaint that no ones returned my call a week ago and was told 5 days for response … still nothing

  • GiveUpTheJosh Forty-Nine Sea Horses (@GiveUpTheJosh) reported

    @O2 Love how you dont respond after you're so rude to me. You wont be seeing my custom again. Cancelling said new 24 month contract, cya.

  • RoLiyanage1 Ro Liyanage (@RoLiyanage1) reported

    @O2 Still waiting for resolution. We he have essentially been sold a completely broken phone and customer service has been terrible. This was a birthday present and in DM we have been assured it will be sorted out . Still waiting for what to do next and a replacement etc .

  • nurdyninja Adam McBride (@nurdyninja) reported

    @BarryMcComish @O2 Hi Barry, I'm currently exploring some legal action against O2 regarding inaccessibility to people with ASD/anxiety relating to restricting certain support to phone calls. You cool if I take a screenshot of your tweet/their reply?
