  • 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.

  • 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

  • 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!!)

  • 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.

  • 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

    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

  • 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

    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

  • 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

  • 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.

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

    @O2 I need a customer call back please.

  • 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

    @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

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

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

  • itsnadine_ abena (@itsnadine_) reported from Harrow Weald, England

    @O2 I changed my tariff now I can’t add a bolt on, if I can’t listen to this mix whilst on a run I’ll cry help

  • 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 !

  • Avigazed Avigazed (@Avigazed) reported from Addlestone, England

    @O2 How long does it take to port a number from another network to o2? Surely 2 days is a bit long.

  • ScottCanEat ScottCanEat (@ScottCanEat) reported from London, England

    Hey @O2.. I #know these are weird times. i placed an order on sunday confimed & paid. online shop says next say delivery is still available. Ive emailed, replied with please use chat. Chats off line. I phoned and only upgrades and leaving o2 calls are accepted. Help

  • RoslynBriggs89 Roslyn (@RoslynBriggs89) reported from London, England

    @O2 is one of the worst phone providers. How can I pay off my contract and still get charged. Your website is overcrowded too. Disgusting and poor service.

  • StinsonTheatre David Stinson FRSA (@StinsonTheatre) reported

    @simonkidwell @VodafoneUK Vodafone are the worst company I’ve ever dealt with! I’m now with @O2 and they are brilliant!

  • Dunxi Duncan long (@Dunxi) reported

    @O2 disappointing customer service from O2 over last few days. Poor that after numerous failures all I get is sorry! Feel you could do more when your staff have made same misquote over and over. Lack of training or a deliberate sales policy? Normally DM but just really unhappy

  • Jane17843158 Jane (@Jane17843158) reported

    @O2 Can you please address the issue of no signal in Biggin Hill it’s been months now that the mast has been broken and not repaired. This is not acceptable fix this network issue now. 😡

  • FF_Diabir Matt Coupland May (@FF_Diabir) reported

    @O2 Yesterday at about 4pm my phone signal at home went from 3-4 bars strong consistent signal to 0-1. I've tried following the troubleshoot on your website, however no solution. Website coverage says no issues in area, but problem is on multiple O2 phones in household.

  • jimscottjourno Jim Scott (@jimscottjourno) reported

    @O2 have just cut my ability to make phone calls after trying to fix a technical issue. They’ve ended up making it worse and now my number comes up invalid. Customer services over phone are useless advising me to wait 24 hours and call back again if there is an issue?!Not good.

  • Raveenix1 Raveenix (@Raveenix1) reported

    @O2 previously asked about issues in Burton on trent and have since messaged the postcode confirming it was a mast issue. Any ETA on a fix? It's been around a month now with no change....

  • jenny_beans18 twiggy (@jenny_beans18) reported

    @O2 can you please tell me why every time I ring to cancel my contract the phone is answered then someone hangs up! 11 attempts I have made to speak to someone. Disgraceful!

  • AJ041987 AJC ⚒️ (@AJ041987) reported

    @tomkentuk @O2 And here's me having an active complaint that has an SLA that hasn't been adhered to. Disgrace. However congrats on the kiddie

  • Leanne157 Leanne Collins (@Leanne157) reported

    @O2 I’ve recently moved and my signal is awful. My calls drop out and no one can hear me on the phone. How do I contact you as I keep getting fobbed off! I pay an extortionate amount each month and can’t use my phone.

  • bellashotton Bella Rodrigues (@bellashotton) reported

    @O2 No phone network for 24 hours and no update on whether the problem is being resolved. What's going on?
