  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

Latest outage, problems and issue reports in social media:

  • Laurenaise Lauren Haigh (@Laurenaise) reported

    @O2 why do I have 50gb of data but can’t load up a webpage? My data isn’t working at all! Hasn’t been all day, what’s going on? There’s no local issues according to your network coverage checker. I pay a lot of money every month to you guys 😡

  • emmajoanne1 Emma (@emmajoanne1) reported

    @IanDaly15 @O2 You mean Virgin and I really doubt it. Tried to tell them weeks ago their service in my town is having issues, but was told it was fine. I’m not the only one either. Just had enough. I pay a lot of money a month for rubbish service & after many years am considering ditching them

  • Lambpie1973 Chris (@Lambpie1973) reported

    @Gemma_Fox @O2 I’ve been with Vodafone for 22 years definitely get rewarded for being a long-standing customer, Hayley’s got a phone and iPad on the same contract how both discounted and my phone is discounted too and signal is really good I find

  • ellis_capon Ellis Capon (@ellis_capon) reported

    Have @O2 partnered with @virginmedia to deliver terrible service? O2 Signal in London has been awful the past few days

  • Gavin297Smith Gavin Smith (@Gavin297Smith) reported

    @O2 It’s ok. Phoned a friend that sorted it quicker than you got back to me. Also took over two hours for you to reply on your messenger service. Phoned your customer service but the automated system tells you to use the messenger. All in all very poor.

  • mummy_knight Helen K  Nottinghamshire Vlogger (@mummy_knight) reported

    Getting annoyed now @O2 rang them due to loss of service and calls dropping my call dropped and no ones called me back!! On hold again now was on hold just now for over a hour!!! Why promise to credit an account for loss of service and not do it

  • AndrewS01250914 Andrew Scott (@AndrewS01250914) reported

    @O2 Should also add, I'm also a contract customer. Just wanted a PAYG SIM for my nephew. Utterly disgusted with you.

  • PeterCuffaro Peter Cuffaro (@PeterCuffaro) reported

    Just been given the worst customer service from o2 after 20yrs+ of loyalty. Means nothing anymore so moving the whole family contracts to another network. Suggestions please? @O2

  • john_houstay John ⭐⭐ & that's my dog Floyd (@john_houstay) reported

    @O2 Thats fantastic however I drive around a large part of the central belt in Scotland and the mobile signal is pants

  • Gemma_Fox Gemma 🦊 (@Gemma_Fox) reported

    @gilbertxgreen @O2 I feel this! The 2 have merged now so I was hoping for good deals. I loved being with o2 but I’ve seen the signal get worse. The deals get worse and customer service get worse.
