  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Hounslow, England

    @O2 Phone masts are down at my work and home so not good.

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • 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

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Hounslow, England

    @O2 your signal in Hammersmith is a joke. London in 2021 and can’t even make a phone call.

  • Marcus_dd1 Marcus (@Marcus_dd1) reported from Southall, England

    @O2 Hi, my O2 cinema voucher keeps saying that there is a problem adding the voucher. Could you help me to go see James Bond tomorrow please

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • MrsScreech Jess (@MrsScreech) reported from Hillingdon, England

    @O2 please sort out the broken mast in Yiewsley. Only having the capability to make WiFi calls from home for weeks on end is becoming frustrating!

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • 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...

  • GeorgeGower_ George Gower (@GeorgeGower_) reported from Blackwater, England

    @O2 unable to log into my o2 online to upgrade. Password etc is correct, but it’s not loading the page on numerous devices. Is there any known issues?

  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

  • musical_IH Iain Hunter (@musical_IH) reported from Spelthorne District, England

    @Br1tt3n @AppleSupport @O2 I’d imagine it’s more a network issue. My iPhone 12 Pro is gorgeous and hasn’t put a foot wrong

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • 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?

  • NileeshKale Nilesh Kale (@NileeshKale) reported

    @O2 I have requested to keep my number and filled the online form. It is still not actioned and no messages/emails from o2. Can someone help?

  • sorryimrin rin (@sorryimrin) reported

    @O2 why does my phone suddenly have no signal in an area where its always full bars? It doesnt even show the O2 logo at the top bruh

  • JEMonaghan Jessica. (@JEMonaghan) reported

    @O2 please can you explain why on #EE you can get 500mb data for £5.02 in USA but on your network it’s £7.20 a MB and you’ve told me I just hit a £51 limit for doing nothing??? Please tell me how to cancel and leave 😫😫😫😫

  • highburyhartley Chris Hartley (@highburyhartley) reported

    @O2 PLEASE CAN YOU ANSWER YOUR PHONE! You haven't sent me a new sim card, but you are happily charging me for my contract. And I can't get through to you - your automated phone line just hangs up all the time. Your service is appalling. Please get in touch to fix this.

  • Jemandi JK 🌍 (@Jemandi) reported

    I’m in South Africa. The reason for high phone use was to sort out flights, cars etc. It’s a stressful time with great uncertainty. Answer your calls and stop putting the phone down on people. Absolutely shocking behaviour!!! Not good enough. I expect better @O2 2/2

  • Kis4Kandy Kandy (@Kis4Kandy) reported

    @O2 pretty shocking that you do not inform your customers about the billing issues. I need previous bills to complete an expenses claim. Can someone send me this via email? Otherwise I will need to be compensated by O2

  • codemonkey3350 Howard Keane (@codemonkey3350) reported

    Not sure what @o2 did - if anything - but suddenly I’m getting what I would expect in my area on 4G. I’ll continue to monitor it though. Seems odd but never mind.

  • TigerMonarch_ tinseltoes tj 🐅 (@TigerMonarch_) reported

    hey @O2 i know i’ve upgraded my tariff but i wanna add a bolt on to use data immediately. myo2 tells me to call but when i call i’m redirected to the myo2 app. help?

  • 02ch3 Chris May (@02ch3) reported

    @O2 wtf 4g everywhere but it’s like having no internet! Sort it out 02 your network is becoming the shittest network

  • WookiePB WookiePB (@WookiePB) reported
