  • 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!

  • 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.

  • 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?

  • 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

  • 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

  • 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.

  • MarkstanYoutube Mark Stanford (@MarkstanYoutube) reported from Luton, England

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @Alyshaa_134 @O2 Went thro the ombudsman, both them and o2 agreed I had a very low data usage but It’s unreal for me to think I will get signal 24/7. So even when you can prove it’s rubbish, it’s just not quite rubbish enough.

  • BobWriggles ᗷOᗷ ᗯᖇIGGᒪᕮᔕ ✌🏼 (@BobWriggles) reported

    I’d like to retract my previous tweet about @o2 network coverage being pants. I travel around a lot and this week I have been in Cumbria, Anglesey, Merseyside and Shrewsbury. It is in fact consistently NON EXISTENT

  • GaryBushen Gary Bushen (@GaryBushen) reported

    @O2 what a shocking company can’t provide the service they charge for no internet anywhere!!

  • paulhayward200 Paul (@paulhayward200) reported

    @O2 The longer I am with O2 the more I realise it’s like smoking. O2 like smoking is a waste of money it dose not serve a purpose and it bad for your health .In O2 case just been with them causes stress. In other words give up O2 and out them in the bin where they belong.

  • Lil_rabbitfoot 'Yatesy was Roberts' (@Lil_rabbitfoot) reported

    @O2 Yes, My bank said straight away are you with O2 , they said lots of customers complaining since 7pm last night and it’s a known issue yes I have tried restarting my phone

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @Alyshaa_134 @O2 I know exactly how you feel. They have the front to tell me to be patient!!! I’m paying for this! From what I’ve read, lack of investment in infrastructure has meant the service massively dropped very quickly. But they still add new phones to its network!!

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @sammyp_30 @O2 Your in now the circle of hell. Just tweet a compliant and add BBCWatchdog and Which magazine tags. This companies customer service is horrendous

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @HelenCoates4 @O2 Retweet complaint add BBCWatchdog and Which magazine tags. Customer service is appalling!

  • TheRealGillyL Gilly Leach (@TheRealGillyL) reported

    @O2 are your phones open? It rang, music which was so loud my ears are bleeding, had an automated voice saying I was the only one in the conference call (?!) now 43mins later you’ve terminated the call? I want to leave o2 asap as I’m paying for a service I can’t use!!

  • Concern51399133 ConcernedCitizen (@Concern51399133) reported
