    @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

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

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

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

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

    @O2 I need a customer call back please.

  • 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

  • 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

    @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

  • 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”.

  • 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

  • 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

  • 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!!)

  • 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

  • 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

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

  • 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.

  • 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

    @O2 My mum loves her new phone and the customer service was excellent and deserves to be recognised. How do I provide feedback for that individual? Do you have an employee recognition scheme?

  • HyamPhoebe phoe🌷 (@HyamPhoebe) reported

    @O2 your customer service is shocking, not had data that works for a year n half (after multiple hours on the phone to u on several occasions) and when calling to cancel just now I was greeted with sighs and sarcastic comments :) waste of money x

    @O2 Doesn’t tell me when the issues are likely to be sorted though. It’s been 2 days now, how long is work on the mast likely to take?

  • Becca_Rees Becca Rees (@Becca_Rees) reported

    @O2 So I went on the website and when I typed in my postcode it said O2 were aware of the text message issue. Signal is very bad but through Wifi my calls generally tend to come through and always go out fine. I just never receive texts until I’m out if the area

  • jashamilton2 James Hamilton (@jashamilton2) reported

    Ordered a new sim from @O2 - it hasn’t turned up but the emails say I should have it and activate it. No route on the website to speak to anyone, online chat… poor. So resorting to Twitter. #customerexperience #CustomerSupport
