  • 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

  • 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

  • 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

  • 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

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

  • 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 !

  • 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

  • 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

  • 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 😡

  • 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.

  • 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.

  • 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

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

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

  • 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!!)

  • paulalovesmaps Paula Smith (@paulalovesmaps) reported

    Hi @o2 why is my 4G signal practically none existent since you sent the 5G has been added message?

  • iluyimbazi Ivan Luyimbazi (@iluyimbazi) reported

    @O2 It’s something to do with O2 network that the switch doesn’t appear. Please enable it for my plan.

  • heathbateman Heath Bateman (@heathbateman) reported

    @lyndonjonmartin @O2 is that a result of the double jabs? My signal is great. 😜

  • KatBoxall Katherine Boxall ⚒️MPBsS (@KatBoxall) reported

    After renewing the parents phones; @O2 fabulous customer service, thank you!! @VodafoneUK NEVER AGAIN!! Dear God!! 🙄😬

  • sw1ller dave (@sw1ller) reported

    @tweetstrong91 @ShitChester @O2 I was once told by an engineer that chester has to have the smaller masts due to the historical nature of the city, they can’t hold enough data fill up quickly. 3G is actually quicker as nobody is on the network but my phone won’t switch to it anymore.

  • Kkkatie1993 Katie (@Kkkatie1993) reported

    @O2 hello, iv sent a direct message to you please can someone help. Thanks

  • Christhefish86 Chris (@Christhefish86) reported

    @O2 If it was a few weeks I wouldn't mind but its rapidly closing in on 3 months without a signal at home, I have missed so many important calls because people can't get in touch with me, it's a joke. I've been an O2 customer for nearly 20 years but once I can afford to I'm out.

  • ianmichell Ian Michell (@ianmichell) reported

    30 minutes of security questions. Repeating the same question over and over even when the answer is correct. Overcharging with no breakdown of cost or reason or warning. @O2 #o2fail again. Honestly, worst service ever.

  • helenmeltz Helen Melton (@helenmeltz) reported

    @O2 absolutely appalling service from you! I am completely dumbfounded that you keep taking money out of my account despite me making several calls & closing the account down & I’m now being told it will take over 7 days to get it back! If it is actually done this time!

  • TheQuiet1ne Liam (@TheQuiet1ne) reported

    @O2 I have requested my PAC code twice and still not received it. This is not good and feels like you are trying to tie me down with a contract I want out of… someone please sort this out 😩 thank you.
