  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 the phone has been cut twice from two separate convos. Will someone please call me back and tell me why my service has been down all day!?

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • timnisbet tim nisbet (@timnisbet) reported from Hazlemere, England

    The is very cathartic after 25 years with @O2 I’ve left for @VodafoneGroup the o2 customer care and support is utterly woeful. And having given them so many chances I’ve had enough, so over to you vodaphone can you step up

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

  • bedefeltham Bede Feltham 💙 (@bedefeltham) reported from Esher, England

    @O2 @gbuttars I'm trying to access Statements on MyO2 account as well. Says information not available at them moment. Is this part of the fix too? 🤔🙏 Please message here if so and once fixed....thx

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 I was told a number would port over in 3-4 hours. 24 hours I am still waiting. Help please!?

  • ElaineHenesy1 Elaine Sheppard (@ElaineHenesy1) reported from Watford, England

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

  • Rochdale_Cowboy Craig (@Rochdale_Cowboy) reported from Maidenhead, England

    Took out an @O2 account as part of some 'volt' deal with @virginmedia. My god O2 are bad. Apparently you have to wait a few months to access your account online to wait until their systems "catch up" for new joiners. Shouldn't have bothered.

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • timnisbet tim nisbet (@timnisbet) reported from Hazlemere, England

    I tell you this country is going to hell in a hand cart I don’t think there is one company who gives a **** about anybody. First it was @British_Airways now @O2 tried for 4 hours to transfer my phone promised a call back and guess what sweet ***** Adam #serviceisdead

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP please

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • KellyMSanders kelly marie sanders (@KellyMSanders) reported from Bracknell, England

    @O2 hi I waited until the pro max was saying next day delivery to order - it says it right now so I paid my last phone off to order it and ten mins later got an out of stock email. Can you tell me how to cancel everything I just did please?

  • SamGittings1 Sam Gittings (@SamGittings1) reported

    @O2 terrible service? Hardly get anything wherever I go

  • immortal56YT apulife (@immortal56YT) reported

    @EnglandRugby @O2 Honest question whats with Itoje being Mr Undroppable? I havent seen him play well for a very long time. Hes just there. Never does anything. Conceeds a lot of penalties. I Just dont get it. Maybe no better options?

  • chrismayLU Christopher May: Retired (now Emeritus) Professor (@chrismayLU) reported

    well, well, well, a but of rain & wind & once again my local @O2 mast in the #LuneValley is out of service (despite two extended 'maintenance' periods recently when we had no signal for days) - is it too much to ask that #mobilephone #infrastructure might be weather-proof?

  • stcrispin2 Ⓜ️IG 🏴󠁧󠁢󠁥󠁮󠁧󠁿 @Psalm121 (@stcrispin2) reported from Saint Eval, England

    @WillR_1807 @EnglandRugby @O2 Mitchell + Farrell for me. Ford/Smith same issue as both can't stand up to international forwards in the contact. I'm tired of watching England's defence continuously shuffling around the breakdown to compensate passive tackles. Farrell presents no soft option for the opposition.

  • Bruschetta_Boy Boy. Likes basil bruschetta. 🇺🇦 🔯 (@Bruschetta_Boy) reported

    @_AndreaUrbanFoX @O2 Yes. Dunno. Dunno. Dunno. Dunno. Glad to be of help… x

  • Worzelwally Jonny Wall (@Worzelwally) reported

    @_AlexBPsych @EnglandRugby @O2 Being shouting this for while. Only now some of the pundits/media/most blinkered fans are waking up. U20s is always a good indicator and last few years have been very poor.

  • MeganWinfield1 MeganWinfield (@MeganWinfield1) reported

    @O2 Still waiting for a reply from the ‘busy’ complaints department and from the DM I sent you. Absolutely shocking, the ignorance is awful from o2.

  • LouGreg Louise Gregory (@LouGreg) reported

    @O2 Hey @O2 do you know how long the #complaints service take to respond to an email? 19.02.2023 it said we will respond in 7 days and still waiting. Mind you I’m still waiting for my original account set up from the beginning of January 2023. Will anyone from o2 resolve the issue

  • 7btstb7 ⟭⟬♡⟬⟭ (@7btstb7) reported

    @O2 when is the signal / mast problem going to be fixed in the HR9 area? can’t get any signal, it’s been days now, your service is a joke 🙄✋🏻
