  • 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?

  • 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.

  • 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

  • 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

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • 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.

  • 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.

  • emmatrainis Emma Trainis (@emmatrainis) reported from Shenley, England

  • 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!

  • 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.

  • NathanWoolmore4 Nathan Woolmore (@NathanWoolmore4) reported

    @O2 I took it out in Romford in 2021. I was never told that it was a business contract. Please can you help me?

  • MattHume27 Matt Hume (@MattHume27) reported

    @AndyShepherd27 @EnglandRugby @O2 Any 9 would struggle with how the forwards were playing, Mitchell came on and had 5 mins of clean ball and we scored, forwards went back to being limp and Mitchell struggled just as much and made his own errors
