    @O2 Thank you. Whilst you’re here, can you help with my 12 month Disney+ subscription which I was given in Nov/Dec with a new tariff. It overlapped my existing subscription but now says it will end in July. Can this be sorted please?

  • uk_magma UK-MAGMA 🇬🇧 (@uk_magma) reported

    @O2 You want me to send you a PM so you can hide my complaint by taking the conversation private. Your robot customer service person will just highlight your current deals on Samsung and Apple crap which I am not interested in. Do you think I am stupid.

  • jamesfarmer27 James Farmer (@jamesfarmer27) reported

    @O2 your customer service chat team are useless and hopeless and patronising. Attempting to sort an issue Day 5 i despair

    @O2 @holly The irony of having a better signal in Nottingham for 5G because O2s coverage in south london is so shite.

  • mckinsella MCK (@mckinsella) reported

    @O2 how can it be so hard to speak to someone at o2? Stuck in a customer services queue for 25 mins and no end in sight. Your a communications company for heavens sake!!!

    @Ogra_SF @O2 @ThreeIreland When I passed the damn border to Leinster this came up 😠

  • Emzy_17 Emmsey 🌙☀️ (@Emzy_17) reported

    @UswitchUK Hi can you help me, I have purchased a contract through your website and I require some assistance. @O2 are refusing to help me resolve the issue!

  • Johnnyr1970 john rudd (@Johnnyr1970) reported

    @MikeAubury @O2 @ladyTbarber1 Most contracts already had some kind of roaming cap anyway so I don think there is much change here. Like you say, bad PR.

  • Rafa__Paulino Rafael Paulino (@Rafa__Paulino) reported

    @O2 Hi guys, I’m currently in Greece and my roaming isn’t working. When I call 202 it send me to the My02 app, when I access the app it’s saying I am not in the country and can’t use the app. I’m stuck and need help asap!!

    @O2 Terribly embarrassed today at CN Leamington Spa. The server was unaware of this offer. Called HO who said it was only on coffee. Then the code worked for 1 drink. Another call to the HO & I was asked to pay for my 2nd drink. Pls communicate offers down the line before broadcast.
