  • 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

  • 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.

  • 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

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

    @O2 your customer service is an absolute joke.

  • 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...

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

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

  • 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

  • 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?

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

    Got to Love when your on @VOXI_UK using @VodafoneUK Network but your Phone keeps switching between a @O2 Mast and struggling to connect to a Vodafone Mast and both ain't recieving interent 5G,4G or 3G. Myself on Voxi and Nan on Vodafone ain't recieved interent for the past 2 hrs

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

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

  • 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?

  • 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!

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

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

  • 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.

  • julie_virgo1 julie virgo (@julie_virgo1) reported from Croxley Green, England

    @O2 #02priority can't seem to get a code for hairspray.. Can you 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.

  • 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

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

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

  • 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.

  • wrexhamisbest Andy Williams (@wrexhamisbest) reported

    @O2 are you having problems in the ll14 area? I am showing 4G but I can't get on the internet or stream. Been like this for a few days

  • TheRealLamz Huey P. Newton 🥷🏾 (@TheRealLamz) reported

    @O2 the signal in my area has been terrible recently, I only ever have 1 bar nowadays 😡

  • I_am_Leighton_ Andrea ™ 🏳️‍🌈 (@I_am_Leighton_) reported

    Told my mother to leave @o2 before her last upgrade but she didn't. Now she's regretting it. The woman has lung disease and can't talk on phone properly. Do o2 care you're not well. Nope. Appalling service. She's been with them 10+ years too.

  • 1Kwesi11 MA (@1Kwesi11) reported

    @O2 worst customer services and network in the UK. Can’t get through to them and when you do they hang up.

  • AtoThaJToTha enter name. (@AtoThaJToTha) reported

    Been with @O2 for years and have never won a damn thing on priority 😔

  • sustain_kids Sustainable Kids (@sustain_kids) reported

    @o2 #Priority just direct messaged you, can you help?

  • iancarnegieruns Ian Carnegie 🏃‍♂️🏃‍♂️🏃‍♂️ (@iancarnegieruns) reported

    People. Don’t use @O2 Recycle. It’s a con and a rip off. Don’t respond to e-mails either. Absolutely appalling service

  • nick_sutcliffe Nick Sutcliffe 🏳️‍🌈 La! (@nick_sutcliffe) reported

    @O2 As is no mention of the two “customer service” operators who HUNG UP ON ME. Stop quoting from your training manual, and find out where my order is. You have 24 hours to give me a delivery date or I will leave O2 after 17 years and take my money elsewhere.

  • MartinCox0155 Martin 'Snazzy' Cox (@MartinCox0155) reported

    @O2 I have Virgin Media broadband only. I do not have their TV service. I received an invitation to download your Priority app, and use my VM credentials to log in. Will I be able to use this app to not only enable me to use O2 Priority to purchase tickets, but also Priority entry?
