    @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

    @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

  • 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

  • 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

  • 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?

  • 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.

  • 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

  • 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

  • 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 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

  • fevrier_justin JUSTIN FEVRIER 🇩🇲 (@fevrier_justin) reported

    @O2 My contract is up with you all paid up why Am I getting chasers for debt? 🤯🚩 14 years cont service btw

  • Sheikspeare9 AS (@Sheikspeare9) reported

    @O2 so not only do you fail to respond to calls and tweets you send me an invitation to send a direct message and then you completely ignore that too.

  • Sheikspeare9 AS (@Sheikspeare9) reported

    @O2 yet again I am disappointed with your lack of support and poor customer service. You deliberately avoid direct contact with your customers and you fail to help and resolve issues. You fail to support those with health needs who can’t always access online services.

  • ZarinsAndrew andrew zarins (@ZarinsAndrew) reported

    @virginmedia Good news. @O2 have provided me with their Volt benefits. Now just waiting @virginmedia to realise what they are promising in the marketing. I guess in any merger there are going to be one half better at managing change and with stronger customer focus.

  • Dan_T_Mc Daniel Mc (@Dan_T_Mc) reported

    @O2 hi, I've been sent a sim only deal which I was told would have 15gb of data but it only has 5gb. The live chat doesn't work on your website and the phone line just says goodbye because I'm not reporting fraud! What a joke

  • hhidhdbdbd2 Hhidhdbdbd (@hhidhdbdbd2) reported

    @O2 what a joke of a company you are. No compassion for their customers. Customer service is atrocious!

  • whitterz_b Whitney (@whitterz_b) reported

    @O2 not happy. Went to activate my extra and links not working . I received the link on the 4th October, now it’s 4th November. Can anything be done please?

  • LoySinead Sinead Loy (@LoySinead) reported

    @virginmedia @O2 I was told i couldnt have this package at price offered as i already am an o2 customer. So as per usual being a loyal customer to both companies i face being penalised. Please explain.

  • 1merritt79 Jamie Merritt (@1merritt79) reported

    @O2 hello, trying to add a bolt on as I've run out of data again. I've just changed my tariff but now I can't add a data bolt on and need it desperately for Friday - can you help please. Thank you.

  • pixomanic pixomanic (@pixomanic) reported

    @O2 Well I got email saying thanks for being with us as long time customer here’s some music on us. But apple won’t give me the promotional period
