  • 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.

  • 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

  • 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!!!

  • 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

  • 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!

  • 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

  • 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.

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

    @O2 dm pls. I have a problem

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

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

  • 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.

  • 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

  • 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

  • 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).

  • 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?

  • 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..!

  • 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!

  • 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.

  • BromptonBumbleB 😷 Bumble B the legend! 😷 (@BromptonBumbleB) reported

    So once again in overseas in Spain and I can’t get any internet access other than free Wi-Fi. @O2 Should be so much hassle to get same service in Europe. #roaringfail again

  • GazWeetman Gaz Weetman (@GazWeetman) reported

    @O2 Thanks for the swift reply. I tried to turn off “automatic network selection” and it just did the ‘buffering’ sign for minutes without producing any other options?

  • HezBarr Heather Driver (@HezBarr) reported

    @O2 currently in London with a 5g capable sim and phone yet only getting 4g! My hubby with same phone can get 5g. Don't know what's happened to my phone help!

  • BrianCo48405777 Brian Cope (@BrianCo48405777) reported

    @O2 Perhaps you'd give me the courtesy of a reply to my reply. As things stand O2 have locked up £25 in a sim. Please advise how this problem can be resolved.

  • PunitGoyal1 Punit Goyal (@PunitGoyal1) reported

    @virginmedia Part4: same team also advised me to get a O2 sim, saying that if I add that sim to my existing package, I will get 4£ per month discount. Which I didn’t get. Upon talking to O2 customer care, they said loyalty discount is for older customers. @O2 @TheO2

  • crels Crels F (@crels) reported

    @O2 what is the process for porting my number onto your network. Keep getting cut off from your telephone customer services. I have the EE PAC code. Thanks.

  • jjacqqui Jacqui (@jjacqqui) reported

    @O2 can you tell me if, when I reach my data cap of £51 for using data outside Europe zone/uk, my phone will cut off? I can’t find answers to this anywhere. I need to add more data from Morocco but don’t know how. Stuck in crazy driving situation + no Google maps! Help!

  • Richie0079 Richie (@Richie0079) reported

    @O2 Hi guys, I've dropped you a DM with regards a PAC code not working. Thanks.

  • cupcakebash Michael Beck (@cupcakebash) reported from Irvine, Scotland

    @O2 getting absolutely fed up of not being able to get Internet access unless inside a house or business premises. Get your mobile WiFi signal sorted please. 😠😡

  • glennbtn Glenn Clark (@glennbtn) reported
