  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    If I was a shareholder in @O2 rather than a loyal customer today would be the day I sold.

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    @O2 I rang 202 and they said there was nothing they could do for me, just to change my password Will text that number now, thanks for your help 👌🏻

  • 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

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    My SIM only service with @O2 has packed up inexplicably today; and O2 slow to respond. Anyway I am without phone. So please DM if you need me.

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    @O2 Tried everything. (Apart from trying SIM in another phone). Previously if ever ‘SIM not working’ flashed up all I had to do was switch phone on/off. Not this time. Help!

  • 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.

  • 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

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    Hello @O2 I am back 🙌🏻 after a few years with no signal, awful service I have come back with my tail between my legs 🙈 #ohtohavesignal 🥳🥳🥳

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

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

  • akasha303 Greg Meeres (@akasha303) reported from Twyford, England

    @O2 Your web chat support team advised I ‘needed’ to call Equifax, rather than Experian, even when I queried (as I have an Experian account). Might want to check the process playbooks! (Issue is now resolved through a work around).

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

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

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • SaintGeorgie Georgie Tongue (@SaintGeorgie) reported from Wokingham, England

    @O2 I spent hours on chat to your advisers trying to cancel my phone contract and was told it was all done. I started a new contract with another provider and now suddenly I have been started on a new o2 tariff??? Help!

  • Jenzy84 Jenna Christie (@Jenzy84) reported from Wokingham, England

    @O2 sort out your customer services ! Waited ages and because the operator didn’t like me saying how ridiculous the service was he cut me off!!! #disgusted

  • 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!

  • 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?

  • aamer74 aamer habib (@aamer74) reported from Maidenhead, England

    @O2 @England My ba p2 priority codes for the cinema are not working

  • nickysinclair Nicky Sinclair PGA (@nickysinclair) reported from Windsor, England

    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

  • Bikeit_UK BikeitUK (@Bikeit_UK) reported

    Be mindful of connecting @O2 worst, sorry no customer service whatsoever. #o2 staff unable to understand and resolve account issues leaving me with a barred phone. Honestly worst #telecommunications experience ever. #ofcom help me

  • pcorless Paul Corless (@pcorless) reported

    @O2 Is anybody able to offer an update of what is happening with this mast. Another week and still not fixed. Why do we have to keep asking for airtime refunds for lack of service they surely be automatically applied to all that are being impacted by this prolonged mast outage. @O2

  • annamarieesss anna-marie ❄️ (@annamarieesss) reported

    @O2 had no signal since yesterday afternoon? Can you tell me what’s going on?

  • Samueltennant Sam Tennant (@Samueltennant) reported

    @O2 over a month ago I Emailed O2 with the evidence of a Contract taken out falsely in my name, they are now defaulting and my CRating is taking a hit. No-one at O2 has contacted me. I have provided all the records and details from the fake TransUnion search. Please help me.

  • edwards_elektra Elektra Kosh Edwards (@edwards_elektra) reported

    @O2 Thanks for that. The agent sent me a link to cancel... All good

  • rosamenti3 Rosa Menti (@rosamenti3) reported

    10/? for my father's account? 2-4 accounts, and we only know of one of them, which, although out of contract, we are unable to cancel because @O2 are uncontactable. Conmen, screwing over vulnerable people who do not possess the resources to negotiate or fight back.

  • TwigsRN TwigsRN (@TwigsRN) reported

    @O2 thanks for your amazing service not!! Lost out on tickets to the national aquarium thanks to your poor data. Think I'll have to cancel my new contract. Thanks again not!!!!!

  • genty1970 chris gent (@genty1970) reported

    @O2 Nice reply… but this has been a long time and when other networks don’t have the same problem I think it’s just o2 as even Fred flintstone who sits next to me at bolton wanderers ground can get a signal on pre 1990s phone when I can’t

  • MattCx90 Matt (@MattCx90) reported

    @O2 You should be, you've lost a new customer 👍

  • AJimWilson Dr Jim Wilson (@AJimWilson) reported

    @TheO2 @O2 Should have no trouble rustling up a new roof! Given the recent price hikes you could probably laminate £50 notes and use those to patch the hole
