    @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?

  • 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.

  • 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.

  • 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

  • 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

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

  • 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

  • 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

  • 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

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

    @O2 are you having some issues? I've been a customer of yours for over 15 years and now I can't log in to your website for some reason?

  • Nino7 Neena Dhana-Finnis (@Nino7) reported

    @mrsball0412 @O2 Better buckle up for a long wait, I've had no signal since 16/9

  • pharon09055299 pharon (@pharon09055299) reported

    @O2 have you got a number for referrals thats not 0800 as I got a email to call them about an order but I am deaf and use the relay app and 0800 doesn't work on it thanks

  • aimsbutler24 Aimee (@aimsbutler24) reported

    You never sent an email or texts to say you would attempt to deliver these dates either or no email to even say you had the item. It’s now back with @O2 and we’re struggling to get it redelivered but we’ve been charged for it. We’ve emailed, tried to call & tried the WhatsApp

  • UUnlocks Uk-unlocks (@UUnlocks) reported

    @O2 could you please advise me on how I can cancel an order and terminate my contract please ? For 2 days I’ve been messed around with and lied to. Not a single advisor can give a straight answer.

  • SuveenGurung suv (@SuveenGurung) reported

    @iAgree3212 @EnglandRugby @O2 Nah but what would’ve helped was Farrell getting the penalty when we we 15-9 down that would’ve put us back in The game

  • Nino7 Neena Dhana-Finnis (@Nino7) reported

    @O2 @EugenAvram5 Very handy guide, but useless team who won't fix the masts that go down!

  • stevenrolfe steven rolfe (@stevenrolfe) reported

    @O2 good morning please could you look into the service in the YO30 area of York? For the past 2 months I can’t even make a call in the area I live I have to use what’s app or messenger in my own home through Wi-Fi as no service, there is no 3G or 4G let alone 5G in the area so

  • Nino7 Neena Dhana-Finnis (@Nino7) reported

    @O2 @GoodThingsFdn @virginmedia That's a big promise when it's taken you almost 2 months to fix a mast, which by the way isn't fixed yet! My newborn will be 18 years old before you actually do something about it

  • sugarteacup Fiona (@sugarteacup) reported

    @O2 Hi there - I managed to resolve the problem in the end, but it was a little alarming when the website told me that my phone number wasn't recognised. :)
