  • RoslynBriggs89 Roslyn (@RoslynBriggs89) reported from London, England

    @O2 is one of the worst phone providers. How can I pay off my contract and still get charged. Your website is overcrowded too. Disgusting and poor service.

  • 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?

  • KevinWNewman Kevin Newman (@KevinWNewman) reported from London, England

    @ianvisits Pointless arguing against the machine 🤖! Take your business elsewhere Ian. I’m sure @EE or @O2 will be willing to help out!

  • joe_bignell Joe Bignell (@joe_bignell) reported from London, England

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • 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

  • rfothergill Ricci Fothergill (@rfothergill) reported from Brentwood, England

    @O2 Nothing received. When was it sent? Last message I had from you was an auto responder on 24th July stating that you’d respond to my complaint within 5 days. Have had nothing since.

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • LeftWingBill LeftWingBill #GTTO (@LeftWingBill) reported

    @O2 Hi I can't access help on th website. I'm trying to bring my number over from EE.

  • Metal_Militia_X Metal_Militia_🖤 (@Metal_Militia_X) reported

    @O2 hi can you please help? I would like to change my number but the only way I can do it by calling 202, but when I call the number, it just hangs up? What can I do please?

  • bri0142 bri0142 (@bri0142) reported

    @O2 any news on when I will be able to receive calls and texts. I didn't join you for half a service. Load of **** you've been so far

  • Peely1973 Peely (@Peely1973) reported

    Upgraded @O2 after speaking to a young lady called Nikki (from up north). Not because she convinced me, because she seemed to actually care. Ensure you commend her for her approach. Ps - I nearly left due to phone signal being nonexistent at Leeds Festival. Sort it out for 2022!
