  • 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?

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • mrtuition frank (@mrtuition) reported

    @O2 are there REALLY any odeon tickets now. For the past 3 WEEKS there are none as soon as the offer goes live. This never happened last year whatsoever. Are you lying to your loyal customers of many years??😡😡😡 pls respond and don’t just say ‘it’s a really popular offer’ etc

  • richa_michael Michael Robert Richa (@richa_michael) reported

    @O2 I have had no service since the middle of September I have been using your network checker which has been telling me there's a problem with the mast. You've used every excuse and still not fixed I'm disgusted with the service and I deserve a refund on my bill

  • RandomM02176892 Random Man (@RandomM02176892) reported

    @O2 Yeah - still not working, even tried on a different device

  • tay100922 (@tay100922) reported

    @O2 hi can you please tell me why I’m paying £80 a month when I can’t even use my phone without internet?? My phone never loads properly and videos constantly buffer

  • karunabegum Kay (@karunabegum) reported

    @O2 This is is probably the 6/7th week. Please don't give me false hope. I have gone through the trouble of doing a screen recording to show u how impossible it is.I find it quite offensive you telling me to try again next week.I have mentioned before I have tried for several weeks.

  • tomlister Tom Lister 💙 (@tomlister) reported

    I am just royally fed up with @O2. The signal is shocking. I can’t sustain a phone call because it sounds like I’m under water and their answer is use Wi-Fi calling but the data is also shocking so that can’t work either.

  • dazza7850 Darren Summerscales-Heard (@dazza7850) reported

    @tomlister @O2 I’m in the same boat. Pay ridiculous amounts of money for 4 devices and they can’t keep me with signal

  • kevgraster Kevin Graham (@kevgraster) reported

    @O2 We’ve moved sim to another phone, tried a different providers sim. Currently waiting on a new O2 aim to try…but I don’t hold out hope. You text today saying network issues resolved. I got 20 mbps connection for 30 mins and then back to the same.

  • Mythical_Siren1 🧜🏼‍♀️ Mythical Siren 🧜🏼‍♀️ (@Mythical_Siren1) reported

    @O2 Is anyone going to respond from @O2 ? I have had awful service locally for months and I am not hearing from you? Not acceptable to state a mast out of action it’s been like this months n months and getting worse

  • join4te Jay (@join4te) reported

    @O2 Day 73 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.
