  • ConlethKane Conleth Kane (@ConlethKane) reported from Hounslow, England

    I’ve been with @O2 for 7 years. I’ve been trying to negotiate an upgrade over the past 24 hours and it has been an actual nightmare. Really bad customer service.

  • Gigiryche Gianluigi PAGHI (@Gigiryche) reported from Harrow Weald, England

    Thank you @o2 for telling me now that you can’t solve my issue with @Apple Watch because “it is not a necessity device”. However when you publicised the deal “AppleWatch plus iPhone”, at the time of my purchase no one at the store mentioned “it’s not a necessity device”.

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

    @O2 I need a customer call back please.

  • AnnKerridge Ann (@AnnKerridge) reported from Wokingham, England

    @O2 It'd nice to see that o2 take customer complaints seriously! Just as about as seriously as using there o2 guru chat service!! I'm still waiting for a reply to my DM that I sent you over an hour ago (about the length of time I wasted on the guru chat service!!)

  • joe_bignell Joe Bignell (@joe_bignell) reported from London, England

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • 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.

  • JoeAchilles Joeachilles.com (@JoeAchilles) reported from Denham, England

    Mother has been getting scammed by a mobile app service "Lasevia limited" for past 8 ish months, her mobile provider @O2 can't help at all. Looking online this has been an issue for ages yet nothing has been done by O2 😡

  • ColinShaw_CX Colin Shaw (@ColinShaw_CX) reported from London, England

    Unbelievable. I get a survey from @O2 regarding their service. I say it’s poor. They contact me and suggest a SIM card change. They have now cut me off until new SIM card arrives! For 3 days! O2 store can’t help. What a shambles! #cx #fail

  • ukcomic Jeff Stevenson (@ukcomic) reported from Hillingdon, England

    @lollylaura40 @samantha00861 @O2 Hi, I have same problem sky seem to have the best deal, I really don’t want to leave o2 but I can’t justify paying over £56 a month when sky will do the same for £49 and you can get money back with topcashback

Latest outage, problems and issue reports in social media:

  • NicVig Nicky Vignoli (@NicVig) reported

    When you start off wanting to call @O2 to get old phone unlocked, then decide to leave during the call because of how bad the automated phone system is, then when your call gets answered they immediately hang up. Trying to talk to @O2 is like banging your head against a wall. 🤬

  • VES76 Vickie (@VES76) reported

    @O2 2nd contact as no response to the 1st. When is the mast going to be repaired that is causing no network coverage in my area? I'm in BD12.
