  • 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

  • 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 !

  • 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.

  • 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

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

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

  • 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

  • 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!!)

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @inoobkilervip @craigglawson @O2 @BBCWatchdog @monzo It will if dont pay it soon haha. Will attempt to speak to an @O2 customer adviser tomorrow and pay over the phone and hopefully that will work

  • 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”.

  • 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

  • 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

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

    5th day in a row I've had no signal or data through to my phone. @O2 is going downhill. Definately on its way out. This is so poor I shouldav stayed with T Mobile. #O2 #POORCUSTOMERSERVICE

  • 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 😡

  • 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

  • ajw32 ArchaeologistAJ💙💙 (@ajw32) reported

    @O2 hi I can’t access my account at all, either on app or desktop. Keeps saying server is down? I really need on to sort some payments out!

  • thisisjmx J∆MES 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported

    @O2 I've lost count on how many times I've unsubscribed from network updates over SMS & I still get them. The number hasn't been on your networks since 2019. CF644QS. If I DM U, Can U please make sure it is removed?

  • Bravo_10_Bravo Bruce (@Bravo_10_Bravo) reported

    @O2 It’s not just that area though, nor is it a recent occurrence. It’s the same issue everywhere, full 4G or 3G signal but limited data. After 9am getting data is nigh on impossible. Come the end of my contract I’ll be moving networks if there hasn’t been an improvement.

  • gunner712004 Gunner712004 (@gunner712004) reported

    @O2 is the my 02 app down? Just get a blank screen when I log on, tried reloading it

  • Lee_Sainsbury Lee Sainsbury (@Lee_Sainsbury) reported

    @O2 Still didn’t answer the phone but called in….phone collected. Somebody didn’t book it in. Service really gone down hill over the last few years.

  • jenvalentine86 Jenscrine (@jenvalentine86) reported

    @Oilyduck65 @O2 Just RUN to another network

  • Oilyduck65 Darren Richardson (@Oilyduck65) reported

    @jenvalentine86 @O2 Have done already, worst network ever

  • AwkwardWyrm ✨𝐝𝐞𝐩𝐫𝐞𝐬𝐬𝐢𝐨𝐧 𝐝𝐫𝐚𝐠𝐨𝐧🐉🇪🇺 (@AwkwardWyrm) reported

    @o2 I cannot find anywhere on your website how to cancel my contract. It ended in June and auto-renewed without my consent. I don’t want a STAC code.

  • CA_Speaky Craig (@CA_Speaky) reported from Wigan, England

    @WAFCWill @O2 Exactly the same mate… whether it’s in Wigan , Blackpool , Manchester or Liverpool. Always shocking service. Hardly any signal !! Poor service
