  • 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

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • 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

  • 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

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

  • 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

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 I ordered Disney + on 24.12.20 on Priority and have not received an email. Cannot get through on phone or live chat. Please can someone help me

  • 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!

  • 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.

  • MarkstanYoutube Mark Stanford (@MarkstanYoutube) reported from Luton, England

  • 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

  • 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.

  • 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.

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • MissSinister_ Sam (@MissSinister_) reported

    @O2 I got a new sim for my phone and asked to keep my number, this was well over 24 hours ago and was done in the o2 shop. But it still hasn't done anything and my old sim now says that it has no service. Please help.

  • southg8lad D-a-v-i-d ✨ (@southg8lad) reported

    @GreggsOfficial I just activated my @O2 priority free breakfast roll code to use at your Walworth Road branch but their systems were down and they were cash only so wouldn’t accept my code. What a waste of a walk there. Friday ruined. 🤬

  • BryNowPayLater BryNowPayLater 🪑 (@BryNowPayLater) reported

    @O2 and @virginmedia I'm already an O2 customer and with Virgin Broadband, how does one go about doing this Volt business? 👀 Tried doing it via the My O2 app but just takes you on a continual loop through "Are you with both? Go to My O2" "Oh good, you're with both go to my O2"

  • thelogosmith The Logo Smith - Logo & Brand Identity Designer (@thelogosmith) reported

    @O2 Hope you can help. Been going round in circles trying to speak to someone about my network problem on new iPhone. I can't call 02 as have no signal, and I don't have a land line phone. Can you help?

  • wintzed Jack Winter (@wintzed) reported

    @O2 my fiancé ordered a new phone and contract 2 weeks ago - for DHL to say they delivered it on Monday, but they didn’t. Now your customer service team is telling her she has to just sort it with DHL and are doing absolutely nothing about it! Absolutely shocking

  • SeanHine31 Seán Hine (@SeanHine31) reported

    @O2 Hello why I'm I paying air time separate from my main bill, very confusing this got me into trouble with you because of them being on separate tabs and not all in one I don't fancy making an error and getting letters through my door again anyway to put it together?

  • prius10 Jonathan Robertson (@prius10) reported

    @O2 hi, I am trying to redeem my 6 months Apple Music but I get an error saying the code has already been redeemed. Can you help please?

  • Blueboymike1983 Michael D 💛🖤 (@Blueboymike1983) reported

    @O2 Listen mate the signals awful, get 3g on a iphone13 pro, i might aswell be using a nokia 3210

  • ryanyates1990 Ryan (@ryanyates1990) reported

    Not what I needed from @o2 as I've seemingly had my sim disconnected for no reason sometime in the night. I can't even ring customer services to see what's happened. Leaves me unable to call docs/111/ etc whilst I've been unwell the last few days, which ain't great really.
