  • 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

  • RossBrown1_1 Ross Brown (@RossBrown1_1) reported from Wokingham, England

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

  • 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.

  • ScottCanEat ScottCanEat (@ScottCanEat) reported from London, England

    Hey @O2.. I #know these are weird times. i placed an order on sunday confimed & paid. online shop says next say delivery is still available. Ive emailed, replied with please use chat. Chats off line. I phoned and only upgrades and leaving o2 calls are accepted. Help

  • 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 🙁

  • 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

  • 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.

  • 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!!!

  • 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!

  • 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?

  • oliviakhwaja Olivia Khwaja (@oliviakhwaja) reported from Sunningdale, England

    @O2 great marketing activity. But no good doing that if you can’t provide basic service. Have been trying for 2 weeks to buy a new SIM. Passed around everywhere, 40 minute waits, given phone numbers by your South African call centre that don’t work. Not feeling like centre stage.

  • 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.

  • 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?

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 I need a customer call back please.

  • 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.

  • 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

  • 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

    @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

    @O2 My nana. she doesn’t have twitter but she deserves a treat :))

  • Lauras95 Miss L Stephenson 📚👩‍🏫 (@Lauras95) reported

    @O2 The issue with my phone has been partially resolved but now when I put my memory card it goes back to being faulty. All my music and photo's is on my memory card and it has never been an issue before, so I don't understand why it is now causing the phone to be faulty.

  • FionaHaigh2 Fiona Haigh (@FionaHaigh2) reported

    @O2 customer service is an absolute nightmare. Had my phone stolen and I waited nearly an hour and half to report it. Not only that, new sim doesn’t work and customer service continues to cancel phone call despite website telling me to call! So disappointing

  • StephaniieJane Steph (@StephaniieJane) reported from Great Milton, England

    @O2 have given me a faulty phone yet I have to go without while they fix it 👀

  • CharlxtteM Charlotte (@CharlxtteM) reported

    @O2 hi, I've waited about 25 mins to get through to cancel my contract and as soon as I checked to see if they would ring back if we get cut off, because that seems to conviently happen, and the person has now left us on hold (for a long time) without even notifying

  • mici55 Michael Ward (@mici55) reported

    @O2 your service is absolutely terrible I've been with you with 2 phone lines for 10 years , you've lied to me, dismissed me and I've just found out, ripped me off I will scream at the top my voice of how pathetic your service and coverage is

  • bristolboudicca Karen Frances (@bristolboudicca) reported

    Not sure if anythings wrong at @O2 but signal in Bath was very poor today making it very hard to catch up with my friends …

  • voiceoverpaul Voiceover-Paul Berry (@voiceoverpaul) reported

    @O2 why is the 'suggested upgrade' to an S21 set at 20gb data minimum...yet if I go elsewhere on your site I can edit it down to 5gb?

  • Annief54 Anne Fowlds (@Annief54) reported

    @O2 if I could afford would cancel my contract with 02 just awful providers in my view, nine times out 10 u may get one bar but even if u get two or 3 service so slow. Not happy

  • Esm955 m (@Esm955) reported

    @O2 i need help, travelling abroad today to finland & can’t get through on phone or the app, will it be ok to use my phone there ?
