  • 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 😡

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @cleggytaxi @O2 Yep you’re right. Signal dropped again.

  • 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.

  • peter33266430 peter (@peter33266430) reported from Slough, England

    @O2 o2 people 02 Twitter the slowest repliers it been - hour still no reply about my complaint

  • 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.

  • 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.

  • 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!!)

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @O2 It doesn’t work. Back doing same lose of signal again. Happens at random places and times around london. Seriously thinking of switching back to #Three

  • ShahlaaTahira 💟 (@ShahlaaTahira) reported from Hillingdon, England

    So now I’m without a phone and will never know where or what happened to my iPhone all because of poor customer service from Hassan in the @O2 Lewisham Branch! So much for customer service! #disgustedcustomer @BBCWatchdog

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

    @O2 I need a customer call back please.

  • 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

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • 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.

  • 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

  • paullferrer Paul Ferrer (@paullferrer) reported from Harrow Weald, England

    @O2 Two weeks later still have low signal and no one is telling me when it will be fixed you pass me to Sky Mobile who say its your masts they use and contact you

  • 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”.

  • JoMeeres Jo Meeres (@JoMeeres) reported from High Wycombe, 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

  • DaSquidinator #DefundTheBBC (@DaSquidinator) reported

    @SkyHelpTeam @tescomobile About time you ditched @O2 as your VMNO partner... Their network is CRAP!

  • shazz_marie1979 shazz davies (@shazz_marie1979) reported

    @O2 does anyone ever actually win. Been doing every priority competition for 2 years and never win a single thing

  • Link2076 LinkoVitch (@Link2076) reported

    How come I get messages from @O2 telling me there is work in my area to improve service, and now I get a text from them telling me using WiFi for calls may be better quality... So pay for a service but don't use it is the message I guess?

  • char_charmed 💥🧙‍♀️🔮ForeverCharmed🔮🧙‍♀️💥 (@char_charmed) reported

    I swear to god i won't be paying my @O2 bill this month if they don't sort out their network!..

  • Mabbannerman Martin Bannerman (@Mabbannerman) reported

    @O2 Nope, pretty much everywhere now. So frustrating buyt it's not just me, people I'm with now on O2 also can't access data despite having "full signal" and apparent 4G. Right now I'm in Leicester City centre!

  • AnnaLambertini Miss Lambert MCCT (@AnnaLambertini) reported

    @O2 Got a new phone. Neither old or new sim work in the phone. HELP! Can’t call for support. What should I do?
