  • 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.

    @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

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

    @O2 trying to upgrade on app and main website but when I choose it crashes can anyone help

  • 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!

  • AEgbuonu ARIBBUZZ (@AEgbuonu) reported from Welwyn Garden City, England

    @O2 sort your cancellation team and phone problem out. #poorcustomerservice

  • 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

  • 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

  • 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

  • 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?

  • 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.

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

    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

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

  • 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

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

  • No1male Paul Shine (@No1male) reported

    After nearly 24 hours of trying to get @peterkay_co_uk tickets I finally get on the site that has been down the whole time, and shock horror all tickets have sold out. Utter shambles! Thanks @O2 #nopeterkayforme

  • ArtisteLtd ArtisteApparelLtd (@ArtisteLtd) reported

    @O2 How are you sold out? The app wasn’t working all day yesterday you then put a post up saying you making improvements and it’s doing the same thing today! Get to a login code even though I was logged in perfectly fine two days ago for it but then crashes 🤬🤬🤬🤬

  • arking84 Andy King (@arking84) reported

    @O2 priority still down? So no chance of getting these “priority” Peter Kay tickets then. Cracking.

  • debsinindia Deb Coles (@debsinindia) reported

    @virginmedia @O2 Priority app STILL not working 🤬

  • tweetvica Vicky A (@tweetvica) reported

    @O2 How is that possible?! They can’t have sold through priority? I can’t see 1 single o2 customer who got through! This has totally backfired I’m switching this was the icing on the cake of always having AWFUL SIGNAL! Perhaps you just let new Virgin customers get through

  • sroles81 Steve Roles (@sroles81) reported

    I don't always use the #O2Priority app, but for the second time now, it has logged me out, prob due to updating. When I try to login via my O2 account, I am presented with a blank white screen. Tried reinstalling, no change. So unstable! @O2

  • sansevieria00 S 🌿 (@sansevieria00) reported

    @O2 What an absolute disaster, you should be ashamed. Just moved to o2 and so this on top of the awful signal/lack of 4G and 5G, I’m feeling like I made an extremely big mistake

  • razorwire00 Rob Sharp (@razorwire00) reported

    @O2 You're a joke. An ISP that can't host a web server and have absolutely no systems in place to stop bots from bulk buying tickets. Absolutely disgusting. Your priority tickets are now on sale via third party sellers at astronomical prices. Absolute **** show

  • lmannis81 Linsey Mannis (@lmannis81) reported

    Is it appears that @o2 priority still hasn’t got it’s **** together !!!

  • wearepetulant Marc Leighton (@wearepetulant) reported

    @Kellyh2203 @O2 I know! That’s my free bacon sandwich down the drain….
