  • bukachef Fine Chef Damilola🥰 (@bukachef) reported from Harrow Weald, England

    @O2 dm pls. I have a problem

  • HarryRobertson5 Harry Robertson (@HarryRobertson5) reported from Bracknell, England

    @ThreeUK been a loyal customer for 6 years, recently brought a new contract through you, yet my upgrade price is far from being a loyal customer, I cant even get an existing customer deal unless I take out a third contract, what a joke! Even @O2 are cheaper than what I was told

  • 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).

  • 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.

  • bethanyxhewitt Bethany Hewitt (@bethanyxhewitt) reported from Bracknell, England

    Experienced some of the worst customer service to date!! First the advisor takes £400 more than agreed, next I’m chasing advisors everyday for a month with false lies about refund dates @o2 #notacceptable

  • 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.

  • 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

  • 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 🥳🥳🥳

  • ninavdbennett Nina Van Driel (@ninavdbennett) reported from Windsor, England

    @O2 I am sorry but I am simply shocked at your poor customer service. I have now called twice to complain and ask for help. Twice I have been told a manager would call me. Twice this has not happened.

  • RoslynBriggs89 Roslyn (@RoslynBriggs89) reported from London, England

    @O2 is one of the worst phone providers. How can I pay off my contract and still get charged. Your website is overcrowded too. Disgusting and poor service.

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • owengmusic Eoghan (@owengmusic) reported from Bracknell, England

    @o2 Ive transferred over to another network but I cant use my phone because you wont unlock it after 2 store visits (Wandsworth and Bracknell) very frustrating

  • Ricardo_7united 🔻ᏒᎥፈᏂᏗᏒᎴ ᏕᏗᏁᎴᏋᏒᏕ/Ⓡⓔⓓ ⚽️🥅🎮🍪🍻 🔻 (@Ricardo_7united) reported from High Wycombe, England

    @sophdefoe92 I had that problem on @O2 but managed to sort it out

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

  • 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!

  • siegeism siege (@siegeism) reported from London, England

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • 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!

  • HarryRobertson5 Harry Robertson (@HarryRobertson5) reported from Bracknell, England

    @ThreeUKSupport I want the note 20 4g but was told for 30gb £58 a month with a upfront cost, where as my "customer exclusive offer" was £55 a month. Or I can can to @O2 and get 90gb for £51 a month with a less up front cost. Talk about customer loyalty!!!

  • love_kittyket Katherine Stephens (@love_kittyket) reported from Hillingdon, England

    Trying to contact @O2 about my bill. But your live chat unavailable, your phone service is limited and cuts me off and my O2 app not useful in helping me.

  • barnoldsays Barnold (@barnoldsays) reported

    @O2 @melwilks What is with the cookie cutter responses to this question? So the price increase is solely because you're investing in your network? Balderdash. Have a terrible day.

  • melwilks Mel Wilks 🏏💻☁️ (@melwilks) reported

    @O2 Your network is terrible. Your 4G barely works in Devon. 3G if you’re lucky. No sign of 5G. So what exactly are you investing in other than your profits?!? No answer to either of my questions. I’ll be leaving at the first possible opportunity once your restrictive contract allows

  • Nerd_with_bird Vix M (@Nerd_with_bird) reported

    @O2 I now have a new SIM card as you were convinced that was why my data was slow and barely signal. Nothing has changed, in fact it's worse. It says I have 4g at the top of the screen but nothing loads, claims I'm offline, speedtest can't find you. Honestly I'm done.

  • Heather_1705 H... (@Heather_1705) reported

    @O2 hi, my mum isn’t receiving text messages to her iPhone 11 from non iPhones, I’ve trouble shooted with Apple and it still isn’t working. Can you help? I’m o2 and my phone is fine but mum isn’t getting texts that aren’t iMessages 🤔

  • ben_pendery Ben Pendery (@ben_pendery) reported

    @O2 @LegendLarry_ Hey, I've tried on Odeon App and private browsing window and still doesn't work. 😔

  • TheRealAMcKay Alastair McKay (@TheRealAMcKay) reported

    @O2 iPhone 5s Never used the app before now. Decided to use it to top up. Had to use the web instead.

  • gorners Phil Gornall (@gorners) reported

    Been with @o2 well over 10 years, whilst not the cheapest always felt value for money with the good overall service, price rises reasonable as per their T&Cs, but whichever idiot signed off a close to 12% annual ‘standard’ price rise at this time is either brain dead or sadistic

  • LegendLarry_ Larry Laher (@LegendLarry_) reported

    @O2 @ben_pendery Have just sent a DM with my code as well. Attempting to use it in Leicester but again no luck. Can you help with this please.

  • whartonsj Stuart Wharton (@whartonsj) reported

    @O2 @MichaelSniedzeH Will you reduce your prices when inflation comes down!?

  • kristianlisle kris (@kristianlisle) reported

    @O2 @UswitchUK By far the best network . Disappointed today I got a call to upgrade but prices too high . The sale person wouldn't let it go trying to sell me a tariff for a tablet and then even a watch . Your price was cheaper online than what she offered 🤔.
