    @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

  • 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

  • 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

  • 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.

  • HaleAlexander Alex Hale (@HaleAlexander) reported from London, England

    @O2 @RugbyXOfficial What a shit show the organisation is at the O2 tonight.. #nopoint

  • 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

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

    @VodafoneUK I have spent three hours of phone time trying to resolve a mistake that your company has made. I am so glad I went back to @O2 PLEASE BE WARNED .... Vodafone customer service is the worse !

  • 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

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

    If your an @O2 customer be careful I’ve had emails and texts saying I owe my bill and I checked through my App and I don’t owe anything. #FraudAwareness

  • 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

  • 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

    @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.

  • 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

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

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

  • 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.

  • 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

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