  • 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!

  • 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.

  • 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!

  • 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.

  • 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?

  • 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.

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

    @O2 dm pls. I have a problem

  • 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).

  • Avigazed Avigazed (@Avigazed) reported from Addlestone, England

    @O2 How long does it take to port a number from another network to o2? Surely 2 days is a bit long.

  • 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

  • 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 🥳🥳🥳

  • 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

  • maryhippychick m a r y (@maryhippychick) reported from Hounslow, England

    @O2 I phoned up customer services who passed it onto the fraud department. They ( customer services) were extremely understanding. I haven spoken to your fraud department.

  • itsnadine_ abena (@itsnadine_) reported from Harrow Weald, England

    @O2 I changed my tariff now I can’t add a bolt on, if I can’t listen to this mix whilst on a run I’ll cry help

  • 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

  • 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.

  • 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!!!

  • 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

  • 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.

  • PeggyFi PeggyFi (@PeggyFi) reported

    @O2 Hi, still no data in Glasgow area. This is now day 4. Are customers affected by your mast issues going to be getting a discount on their bills or at the very least an update as to when they can expect to be able to use data again?

  • nest_head Barry Connolly (@nest_head) reported

    @O2 why is you network coverage so 💩

  • Loistime Lois Forster (@Loistime) reported

    @O2 any reason why your data is particularly bad today? We’re on o2 data and VM broadband so have struggled particularly today…

  • GreeneJJ18 John Greene (@GreeneJJ18) reported

    @O2 Still without service.

  • Slug_a_otoole Simon Crossley (@Slug_a_otoole) reported

    @O2 I’ve got signal and I’ve got 4g it just doesn’t work and you know about it because I’ve just found out you’ve refunded a neighbour his airtime! Sk27qd sort it out please!

  • Meeesterpablo Paul 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺 (@Meeesterpablo) reported

    @O2 Just back from the USA - data was throttled to the point where it is almost unusable. I was getting <1Mb download speeds in Orlando FL despite full reception. Will buy a US network SIM in future and downgrading my 02 plan to remove the Travel Inclusive bolt-on.

  • charlottie76 Charlotte Grundy (@charlottie76) reported

    @O2 I swapped over to o2 a few weeks ago from 3. Just after the end of the 14 day cooling off period my mobile data stopped working. Where ever I go there’s a mast not working-is unusable! I’ve tried the chat function and service checker and both those aren’t working.

  • CLizzle86 Carey Canavan (@CLizzle86) reported

    @O2 Your customer service is absolutely non existent. How hard is it to speak to a manager or anyone who can actually help me?!

  • angeliz35 Carmen Hobbs (@angeliz35) reported

    @O2 This has been an ongoing issue for nearly 2 years. I've been told to change my phone settings which made the problem worse. I can't make or receive calls IN MY OWN HOME unless I go outside. Absurd!!!!

  • StuMc85 Stu Mc (@StuMc85) reported

    @O2 flicked you a DM yesterday, still no response despite a follow up sent this am. DM responses in line with your network speeds.
