  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • 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

  • 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.

  • juliet_gough juliet gough (@juliet_gough) reported from Stevenage District, England

    @O2 I have an enquiry and can’t find an answer on the ‘My O2’ page. Please help. #CustomerService #o2

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

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

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

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

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • 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?

  • sarahcoysgabb sarah gabb (@sarahcoysgabb) reported from Broxbourne District, England

Latest outage, problems and issue reports in social media:

  • _SonOfTheDesert Kaiser Soothsays (@_SonOfTheDesert) reported

    @O2 Data is unusable where I am (Milan). As stated, I get 3G but can’t use it, all apps say phone is not connected to network. Irony is my wife is with @tescomobile and is getting 5G. Crossed into Switzerland today and got 5G halfway up a mountain but can’t use phone in Milan. 🤷

  • Srennie1877 stuart 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@Srennie1877) reported

    @GavNewlandsSNP @O2 The signal in Hampden is awful, it’s the same at st Mirren park so probably just the grounds rather than phone signals

  • AmieBirkett94 Amie Birkett (@AmieBirkett94) reported

    @O2 are the shittest phone network with the WORST customer service ever. A loyal customer for over 10 years and I have had the same issue going on for over 5 months!!!

  • michelle_moomin Michelle Annie (@michelle_moomin) reported

    @O2 Absolutely shocking service at your Cribbs Causeway branch. So much so, a lady followed me from the store to say she had the same issues with them.

  • paul_trombone Paul Emmett (@paul_trombone) reported

    Really helpful that @O2 has been texting my account info to a different number and when I don’t respond they block my service, and moan at me when I call support! Cheers, that’s helpful!

  • JadeyBum1990 Jade Tant🦩 (@JadeyBum1990) reported

    @O2 Went all the way to my next city yesterday to arrange a change in phone, only to get there and be told there wasn’t anything they could do as system upgrades were happening, and at random, numbers weren’t being recognised as customers…Mine being one! 😠 Not great service!

  • ajameson1008 Amy Jameson (@ajameson1008) reported

    @O2 Hi I am the victim of identity fraud. You have allowed someone to open an account in my name with my old address (where I haven’t lived in 10 years) Customer services won’t allow me to call unless I make a payment.

  • SANKALP4664 SANKALP SHIRODKAR (@SANKALP4664) reported

    @O2 is one of the worst service providers having been on the line for past 2hrs and they yet could not solve my problem

  • WaynePT7746 WB(P) (@WaynePT7746) reported

    @O2 Hi, any chance of a response to the DMs regarding MyO2/PAYG issues? Thanks

  • ajameson1008 Amy Jameson (@ajameson1008) reported

    @kellyja90235455 @O2 Me too! Two contracts taken out fraudulently and can’t speak to customer services unless I pay the fraudulent account! Seems to have happened to lots. I’ve never been an o2 customer! So stressful
