    @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?

    @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

  • 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!

  • 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

  • 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

    @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.

  • 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

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

    @O2 frustrating customer service this morning! Trying to activate the Disney plus offer for the kids!!!

  • darrencoleshill Darren Coleshill (@darrencoleshill) reported

    @O2 Still not working

  • PeteDean16 Pete Dean (@PeteDean16) reported

    @o2 is the only way to contact you via telepathy? I am still unable to have a live chat - and your twitter erk merely asked what the problem was and could not be bothered to follow it up…. Two different browsers tried - guess the competition is likely to get looked at !

  • Bob_Skittles David Murphy (@Bob_Skittles) reported

    @O2 tried to cancel my contract and in a que twice for 20mins on hold and you cut me off twice. No surprise worst customer service.

  • Paulfrom68 Paulfrom68 (@Paulfrom68) reported

    @kojecat @O2 @DisneyPlusUK I have been having the same issues

  • dadtostanandnin Aldborn (@dadtostanandnin) reported

    @O2 Yes I read your piece. I phoned @SouthernRailUK and they didn’t charge me £12.50 for FOUR MINUTES. Sorry @O2 I thought you were going to back me up on this since I’ve been a customer of yours for years. Turned your back on me there very fast.

  • JEMonaghan Jessica. (@JEMonaghan) reported

    @O2 I have used my PAC code from you to change networks, will you send any notification and final bill? I was told this was all I had to do to cancel…

  • Griffin_07 Mark Edgar (@Griffin_07) reported

    @O2 It’s not a feeling, it’s a fact. You’ve failed to deliver an agreed service with implied element of time delivery

  • AshishB62545995 Ashish Bhat (@AshishB62545995) reported

    @O2 received my upgraded phone iphone yesterday. received a used phone with marks on the edges. Now that’s a trust issue. Have I never used a brand new phone from O2 . This how you sell upgrades ???

  • alsheard Al Carson-Sheard 💙 (@alsheard) reported

    Hi @O2 is there a problem with your Chat facility on MyO2? I’ve been trying to use it since 10pm last night and keep getting an “all our agents are busy” message. Is there really nobody available to help?
