  • OllyFT Oliver Fytche-Taylor (@OllyFT) reported from Chadwell, England

    @iD_Mobile_UK @O2 @giffgaff As expected, and despite the promises, I have received no call back for a third (and now final) time. Please escalate the complaint as requested - I've had three commitments for a call back only for you to miss every single one of them. Beyond poor service.

  • HeyImMichaela Michaela (@HeyImMichaela) reported from Balderton, England

    @Oh_So_T @O2 I rang up but it wasn't very helpful. My signal is still poor. I have a months credit on my bill though now, so at least I'm not paying for it... Still doesn't help the frustration waiting for stuff to load!

  • bennyjcomer benjamin (@bennyjcomer) reported from Chadwell, England

    Disgusted with @O2 I’ve spoken to them twice on the phone. About my phone not working. First time they just cut the call when I was on hold, second time I was on the phone for 55 minutes and then they said they would ring me back. The second call all I could hear was..

  • markMCFC83 Mark Jones (@markMCFC83) reported

    Very disappointed with the service from @O2. Ordered a new phone 7 days ago with "next day dispatch" on the website. Next day told it would be delayed. Website still days 2-3 days yet O2 themselves say they are unsure when stock available. Very misleading

  • ShelleyRich9 Shelley Rich (@ShelleyRich9) reported

    Very angry right now with @O2 in the uk. Can’t speak to a human at all, DM’d them, was asked a bunch of questions which I answered immediately and now no response and no nearer a solution! No info on the website for my issue!

  • Priya72123478 Priya (@Priya72123478) reported

    @O2 my priority qr code for McDonald's Chicken Selects is not working, it's saying it's already been used. Now can’t use it for anything else either. Please help, Thanks

  • tynn_angus Tynn (@tynn_angus) reported

    @O2 the refund has been dealt with, i received 3 confirmation texts id have it within 7 days of the 2nd of December… i am still waiting. Needless to say i have been left in quite a bad financial position due to this over charge - especially at this time of year!

  • Kyliesmile4 Kylie smile (@Kyliesmile4) reported

    @dan_bevington @O2 Hi it also happen to my account for 2-months and I tried contacting support service but they always have me a robot reply so I got in contact with +1 (707) 653-5170 on WhatsApp, she was the one who helped me activate my iPhone 12 Pro she will help you out

  • BryBryCan Bryony Cannings (@BryBryCan) reported

    @O2 McDonald code not working. Tweeting is apparently the only way for support. First said code not valid and then it had already been used.

  • Katielbee Katie Baillie (@Katielbee) reported

    @O2 hiya, I tried to use the code, at first it said not recognised and then said it had already been used. A little help?

  • Ind3pendent7 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺 Rebel Scot (@Ind3pendent7) reported

    @Fintan_T @Ofcom It’s the simcard that they’ve blocked otherwise I’d use my own old phone. But thanks for the offer anyway. Just trying to complain about @o2 lack of customer service

  • InvestmentBay SBInvestment (@InvestmentBay) reported
