    @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

  • 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

  • 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

  • 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

  • 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?

  • 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.

  • 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!

  • 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

  • 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.

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

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

    @CotswoldLadyB @O2 Totally agree! I am with O2 and in Chalford when home it’s awful!!!

  • natjarvis100 Nat Jarvis (@natjarvis100) reported

    Honestly sick to the back teeth got my new phone yesterday and had nothing but issues with getting the E-Sim sorted not been reachable all day and @O2 wouldn’t speak to my mrs even though I’m not reachable to sort it out!

  • Eva_1908 Eva Smitte (@Eva_1908) reported

    @O2 are your customer support telephone lines down today? I tried to reach them 30 min ago, but was told the lines are closed, while simultaneously being told that they are open from 8 am till 8 pm on the weekdays. 🤯

  • bark_natalie Natalie Bark (@bark_natalie) reported

    @O2 I’ve tried everything: 🔁 Reset network 📲 Changed phones 📡 Manual carriers 📶 Disabled 5G 🛜 WiFi calling Same result every time: one call works, then total failure. #O2Fail #RoamingNightmare

  • NicolaWainwri14 Nicola Wainwright (@NicolaWainwri14) reported

    Been with @O2 for years and years but can honestly say their priority app is a complete waste of time! Never won anything, never had anything useful on there, don't see the point of it at all!

  • azzyface1990 AH (@azzyface1990) reported

    @O2 Have had my device that i returned via Switch Up (that they cleared and accepted) for over 5 weeks and still haven’t cleared the device loan and STILL charge me monthly for it. Even after making 4 complaints. Genuinely the most incompetent network going. Incompetent wankers!

  • marksnowden1981 mark snowden (@marksnowden1981) reported

    @O2 has a slogan of essential for living yet leaving somebody with no phone signal for 2 days is hardly living up to that. Then to offer somebody 3 pound has compensation, absolute joke of a company to deal with

  • ClareEGabriel3 Is it me? 🤷🏻‍♀️ (@ClareEGabriel3) reported

    @CotswoldLadyB @O2 We sacked off O2 on the outskirts of Worcester. It was truly pitiful. We had 2 painful years of truly abysmal service pretty much wherever we went. Went back to @EE hurrah

  • beccau24 rebecca Creese (@beccau24) reported

    @skytv @bt_uk no internet so can’t use my phone no signal and no tv and no internet neighbours said you they were told it might be up to Tuesday all are things in the flat run off wifi and I need to walk all the way out the house to make a call @O2 signal is only one bar no good

  • atypicalbob Bob (@atypicalbob) reported

    @O2 - what’s going on with your service in Kent? Got nada reception.
