    @O2 @TheO2 “We’re better connected” “Be more dog” only thing dog is your 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?

  • 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.

  • 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!!!

  • 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

    @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

  • JonLeePButler Jon-Lee Paul Butler (@JonLeePButler) reported from Fleet, England

    @O2 if a mast in the area is not working, and service checker gives message of 'taking longer than expected' to fix. Would ALL O2 mobiles be affected in the area? Just asking, as mine is without signal but flatmates is with. Odd that. Don't you think?

  • 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.

  • 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!

  • 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

  • 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.

  • 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 🥳🥳🥳

  • 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

  • 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.

  • 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).

  • 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

  • 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.

  • 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..!

  • tobyd360 Toby (@tobyd360) reported from Farnborough, England

    @O2 I’m stuck! Trying to upgrade online, on the last screen realised it was the wrong GB model of iPhone 11 - seemingly can’t cancel it from there myself? And if I go back and click to upgrade again, it just brings up the load screen forever 🙁

  • 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.
