    Anyone else lost @O2 signal?

  • AndrewCarrier Andrew Carrier 🍸 (@AndrewCarrier) reported from Hammersmith, England

    @cgledhill @McDonaldsUK @O2 I think the more pressing question is: Why are you using a public wi-fi network?

  • RoseHinds Rose Hinds (@RoseHinds) reported from Kensington, England

    @O2 hi I’ve been charged extra this month for my phone / Apple Watch bill. Please could someone help me and explain why / resolve the issue

  • SteveHodgson1 Steve Hodgson (@SteveHodgson1) reported from Merton, England

    @O2 are you having power problems in the SW London area? I can’t get a service which is normally excellent

  • VictorJ1987 Vìncere. (@VictorJ1987) reported from Brentford, England

    Thanks @VodafoneUK for the run of 3 poor months of customer service requiring us to request for cancellation. Typical that your retention team could not even be bothered to make an effort. Go and listen to the phone call. I guess @EE or @O2 here I come. #Vodafone #Dontbother

  • Si11y3gg Pawlie (@Si11y3gg) reported from Richmond, England

    @VixSeaman @EE @O2 I’m with o2 also! Was with Three before, but would never bother with EE. I will only do sim only.

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • kostas1903 Esmer Ozan (@kostas1903) reported from Bexleyheath, England

    @O2 The UK’s number 1 network? Don’t make me laugh ! I’ve just switched from Vodafone to 02 and that was the worst decision I’ve ever made 🤬🤬🤬 I barely get 1 bar. My phone keep disconnecting in central london. Calls are always failing. 02 is my disappointment.

  • Brunts1980 Nickle Arse (@Brunts1980) reported from Camberwell, England

    Thought @ThreeUK were bad but @o2 may have to be even worse...

  • martinkay11 Martin Kay (@martinkay11) reported from Wandsworth, England

    Did @O2 iphone recycle thing (diff login to normal O2... would help if they told you 🙄), was quoted £132. Then get message they’ve revised value to £28. 79% reduction. Zero explanation as to why. I’ll have that phone back then #o2recycle All a bit #GreedierO2 than #GreenerO2

  • sladey66 It’s only curly at the front (@sladey66) reported from Camberwell, England

    Is anybody else getting no service from o2? It’s been woeful for weeks @O2

  • SteveHodgson1 Steve Hodgson (@SteveHodgson1) reported from Merton, England

    @O2 Hi, yes I’ve done both. Apps are so slow loading when wireless is switched off and service isn’t great on 3G or 4G. Used to be excellent

  • Munden87 AA Ron 🖤 (@Munden87) reported from Addington, England

    Anyone else’s data slow AF on @O2 constantly having issues with my data speed! It’s driving me insane! Constantly not working in places but full signal!

  • markh4780 Mark Harris (@markh4780) reported from Kensington, England

    @O2 looks like it’s gone down in London!!!! Any update on this would be helpful 🤷🏽

  • KevinWNewman Kevin Newman (@KevinWNewman) reported from London, England

    @ianvisits Pointless arguing against the machine 🤖! Take your business elsewhere Ian. I’m sure @EE or @O2 will be willing to help out!

  • LebbyE Lebby Eyres (@LebbyE) reported from Islington, England

    Essentially @o2 treat everyone who wants to buy a phone under £200 outright like a potential fraudster. You can’t pay it off in store and they force you into a temp contract. Then make you wait hours on the phone and go via their fraud dept. Why? I’d love to know.

  • RoseHinds Rose Hinds (@RoseHinds) reported from Kensington, England

    @O2 Ah ok thank you. I’ve realised that my free trial with Calm has expired - how can I find out how much this is meant to cost? I’ve been charged twice and was not reminded that it would charge me this month please help

  • allyc375 Alison Cameron🐟 (@allyc375) reported from Kensington, England

    @ShieldingG @O2 Now there’s an idea. I wonder where the cleaners put it. I’ve only ever used it for my Dalek thing - never plunged a sink in my life.

  • MCFCLondon Tueartsboots 🐝🌹✝️🇬🇧🇺🇸 (@MCFCLondon) reported from East Ham, England

    @O2 how come i can get a phone signal under the Thames on the Jubilee line but zero signal on Shooters Hill, SE18?

  • Mr_ISC Pasha (@Mr_ISC) reported from Wandsworth, England

    Serious network issues with @O2 - calls not connecting or dropping after 30secs all morning!!

    @O2 is your recycle your phone option on your app not working?

  • AbbeStyles abbecummings (@AbbeStyles) reported

    @O2 such a shame after being a very loyal customer of yours for almost 20 years i was refused a free upgrade. After paying £729 off my £905 device on #refresh plan the £175 couldn't be squashed. Never asked before . Your adviser Hector simply replied not long until april. 👍

  • Chad25216451 Chad (@Chad25216451) reported

    @O2 Honestly @O2 you guys love giving your customers a s*** experience !! It took me 20 minutes just to get past your damn auto service to be placed in a queue 😡😡 literally the auto service took every opportunity to cut the call. What a load of horse 💩 🤬🤬

  • GowanTheBoy David Gallagher (@GowanTheBoy) reported

    @O2 can you cancel an order

  • bats22 Caroline Ward (@bats22) reported

    @O2 After 45 mins on hold I have been cut. System makes it impossible to speak to a human. Such a poor service.

  • patriciawilkin1 patricia wilkinson (@patriciawilkin1) reported

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @O2 if I stop using my O2 contract for 24 months will the contract cancel down by itself due to inactivity?

  • bluesbarbers Wendy KL Martini 🌈🇬🇧 (@bluesbarbers) reported

    @O2 Payment not even due yet & getting txt threats to pay now or your stop my service this is a business account!! & I’m sick of every month having to sort this out it is a disgrace if it happens once more I’m switching to @EE again never had a problem ever with them. App is useless

  • MS45416467 M S (@MS45416467) reported

    @O2 The network coverage is awful, don’t care about existing customers only interested in new customers, I have had network issue since January and still not resolved, The worse network in Uk

  • James_D_Shaw James Shaw (@James_D_Shaw) reported

    Disappointed at @O2 in store. Representative knew nothing of service despite website saying it could be done in store. Situation now resolved by phone.
