  • 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

  • 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?

  • 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

  • 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

  • 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

  • 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 can someone from customer services contact me ... I need urgent help ... Thanks

  • 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

  • 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!

    @PrettyAverageG @O2 Did you sorted it? I’m having the same problem!

  • PC75UK Paul Cooke (@PC75UK) reported

    @ExperianExperts @O2 @virginmedia Hello, I was given a “free phone” by Virgin. They told me it was a virgin mobile but that it was on the 02 network. What they actually did was open an 02 account without my permission and have started to charge me £10 per month for a phone I am not even using and do not need.

  • wendyg4073 wendyg4073 (@wendyg4073) reported

    @O2 The reception in Ayrshire is disgraceful you complain in store it's a mast issue, I'm not getting what I pay for, it's every week we complain time for a change of provider I think, been a customer for as long as I've had a phone and now your just rubbish

    @O2 I have been without phone signal for around 24 hours. Your system error site says that there are engineers working on a mast nearby. (Don't want to give exact area on tweet). Any chance of an update? It's a bit of a nuisance

  • FrancisAllies Francis Allies (@FrancisAllies) reported

    Chasing up @O2 lack of response to my active Volt Travel Inclusive option that isn’t working in USA! Arrived in Philadelphia 24 hours ago, still no update on the roaming issue. New SIM came with @virginmedia package, regretting the switch over and paying for zero service so far.
