  • 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.

  • DanLeahy71 Dan 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@DanLeahy71) reported from Stretton, England

    @EE But was rubbish once I left the city and went home. Hence, I’m still with @O2 who I also got a 4G signal from in the city.

    Laughing & people shouting in the background. Very unprofessional behaviour. Ive also been taking to a robot all day trying to sort this issue. Yet no help! So I’ve been without a working phone most of the week unless I’m connected to Wi-Fi. Not one person wants to help. @O2

  • 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..

  • PhilipFOTBOT Philip Smith (@PhilipFOTBOT) reported

    I have explained to @O2 three times that I have never been to Jamaica. Why is that so hard to grasp?

  • NickPat20265806 Nick Patterson (@NickPat20265806) reported

    @O2 Hi have full 4G signal so no signal issue. And if it’s a network fault do me, my wife and my mate all report it as a nationwide fault, since your speeds are genuinely rubbish everywhere.

  • NadiaDryden Nadia Dryden (@NadiaDryden) reported

    @virginmedia @O2 have had a nightmare today trying to speak to somebody in your organisation who can explain why you have cut off 181 mobile business sim cards whilst attempting to migrate them o2. I now how 181 business mobile accounts down with no explanation..

  • david89eaton David Eaton (@david89eaton) reported

    @O2 You’ve disconnected my service after your agent failed to set me up on a payment plan as requested in mid-July. I’m now completely disconnected, and my phone has essentially now become an iPod Touch. Called from a pay phone and hung up on 4 times. Disgusting. I need your help

  • martincottle Martin Cottle (@martincottle) reported

    @O2 delighted to have been able to get some service after three hours of trying. Awful company. Awful service.

  • PattenStacey stacey (@PattenStacey) reported

    @O2 I would never use this network ever again , they make people have deforts on there credit score , even when you have paid the bills every month , the customer care team are useless and nobody seems to want to help solve there problems don’t waste your time with this company

  • NickPat20265806 Nick Patterson (@NickPat20265806) reported

    @O2 Anyone get usable 4G speeds on O2? Me and wife joined O2 last month and no matter where in the UK… absolute garbage. Note their forum is absolutely littered with identical complaints.

  • LoulouKite Marie Helene Kite (@LoulouKite) reported

    @O2 We have been referred BACK to the shop in Southampton to raise an issue we are trying to sort for 2 weeks now. We were told that the shop manager has full authority to write off the bill we are refusing to pay because the terms of the contract was misleading.

  • rhirhi_bee Rhi (@rhirhi_bee) reported
