  • KJDalby Kate Dalby (@KJDalby) reported from Chelmsford, England

    @O2 urgent my new provider activated the PAC code provided by you. Their sim card does not work because apparently my device is locked with you. I cannot text you to get it unlocked. Please help asap.

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • siegeism siege (@siegeism) reported from London, England

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • RyanSchaverien Ryan_Schaverien (@RyanSchaverien) reported from Chelmsford, England

    @O2 Extremely slow data coverage for the past 3 weeks.... any help?

  • ColinShaw_CX Colin Shaw (@ColinShaw_CX) reported from London, England

    Unbelievable. I get a survey from @O2 regarding their service. I say it’s poor. They contact me and suggest a SIM card change. They have now cut me off until new SIM card arrives! For 3 days! O2 store can’t help. What a shambles! #cx #fail

  • AbbeygaleRose 𝐀𝐛𝐛𝐞𝐲𝐠𝐚𝐥𝐞 (@AbbeygaleRose) reported from Chelmsford, England

    @premnsikka Am moving contracts away from @O2 this week - voting with my wallet and I’ve been a customer for 31 years!

  • theveritas4 Truth and Justice (@theveritas4) reported

    @O2 app and website is not working. Can't access account details. PAYG customers can't top up. Bad bad bad. So much for the benefits of being part of @virginmedia.

  • PremMukkamalla Prem Mukkamalla (@PremMukkamalla) reported

    @O2 Filed a compliant with @O2 over duplicate billing 6 weeks ago- still no response. Absolutely awful customer service. No accountability, no updates.

  • VolcanoAerial Volcano Aerial (@VolcanoAerial) reported

    @O2 Say Hello to increased prices above inflation. That’s right, we will lie to customers claiming it’s for “network upgrades” while simultaneously trying to blackmail customers to remain with the network falsely claiming you can’t keep a device plan and swap an airtime plan.

  • VolcanoAerial Volcano Aerial (@VolcanoAerial) reported

    @O2 I had to push the cancellation team hard @O2 reading back your email to the customer support agent. If I had not done that they would have tried to have made me pay off my device in full.

  • NigelMa20823614 Mr Brooks: Who/Me....ECFC .... it's complicated (@NigelMa20823614) reported

    @O2. Hi I can't login to my O2 app to pay my bill. Can you help please. Thanks.

  • davejoleary5 Dave O'Leary 🇪🇺🇮🇪💙 (@davejoleary5) reported

    @O2 After over 25 years as a customer I have finally made a move, significantly overpaying for too long and more recently just terrible customer service. Very disappointing. Not sure why you would want to run the company down like this.

  • Becci09453535 Becci (@Becci09453535) reported

    @O2 I followed your instructions for perplexity but it has not given me a pro account. Please help

  • Silverlink_ Iyren (@Silverlink_) reported

    Time for me to leave @O2 never get signal anywhere 🥹

  • Webby_213 luke webster (@Webby_213) reported

    @O2 continent for you that when I try to cancel my contract I need to prove it’s me and you just keep refusing. But as soon as I cancel my direct debit at the end of my contract I don’t have to prove anything I just need to pay it. Corrupt as ****
