    @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

  • 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.

  • 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!

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

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

  • 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.

  • 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

  • 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.

  • 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.

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

    @O2 It’s being investigated but there was no indication that they would be back in touch with me. I’m concerned that my address will show up with bad credit with both you and other bodies as a result of this fraud.

  • 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.

  • 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?

  • 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

  • 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

  • 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).

  • 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.

  • 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.

  • 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!

  • 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!!!

  • mancunianbrief Ammer (@mancunianbrief) reported

    @O2 can you explain why I’ve just waited one hour and 45 minutes on your line and still nobody has answered. Pathetic customer service.

  • sparkyshiny Sparky Shiny (@sparkyshiny) reported

    @O2 Your customer service is a waste of time and absolute disgrace!

  • GHAT69 Gerald Tomkinson 🎥 (@GHAT69) reported

    @O2 Had no service all day but the network has just come back tonight

  • kelly51002499 kelly (@kelly51002499) reported

    @O2 trying to pay my accounts via the app ... app will not load anything , same via website , tried on other devices same thing happening , been on to customer services via phone was on hold for a very long time , did speak to someone who was getting everything confused :-(

  • elainehopkins3 elaine hopkins (@elainehopkins3) reported

    @O2 Used the checker.. All OK... Seems its a Google issue

  • mambalovesdaisy Sam 'Mamba' Carley (@mambalovesdaisy) reported

    @O2 There's no physical damage, I think it must be a system thing as it randomly closes apps when I'm using them and the swipe function doesn't always work. It just doesn't function very smoothly for a 3 month old phone.

  • _Kattnipp_ Catt In The Hatt (@_Kattnipp_) reported

    Of *course* my important apps don't load the day after I realise I have no more mobile phone payments #HUAWEI The old Uninstall / Reinstall doesn't fix it. @HuaweiMobileUK @O2

  • CharleeWharlee ♡ Charlee ♡ (@CharleeWharlee) reported

    I keep not receiving text sounds when my iPhone 12 Pro is locked but it’s not on do not disturb or anything, can anyone help? @Apple @O2
