  • 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

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

    @stu_levy1 @Luca__WFC @O2 I've just realised that might be Rick Astley on stage as the support act, sorry.

  • 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

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

    Beginning to regret renewing my contract with O2, their coverage in Chelmsford is awful. My 4G works about 20% of the time. @O2

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

  • 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.

  • 1011FOXEE beverley fox (@1011FOXEE) reported from Takeley, England

  • 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

  • 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.

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @inoobkilervip @craigglawson @O2 @BBCWatchdog @monzo It will if dont pay it soon haha. Will attempt to speak to an @O2 customer adviser tomorrow and pay over the phone and hopefully that will work

  • 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.

  • 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

  • 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.

  • 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?

  • ScottCanEat ScottCanEat (@ScottCanEat) reported from London, England

    Hey @O2.. I #know these are weird times. i placed an order on sunday confimed & paid. online shop says next say delivery is still available. Ive emailed, replied with please use chat. Chats off line. I phoned and only upgrades and leaving o2 calls are accepted. Help

  • Paulc2nd Paul Curry (@Paulc2nd) reported

    @O2 How do I raise a complaint with you ? Two separate advisors have refused to transfer me to payment management because I refuse to go through security twice

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • Fader209 Andy Plumbly (@Fader209) reported

    @O2 Hello O2, I have had troubles making calls for nearly a month now. Your site says there is a problem with the local mast but 4 weeks seems a bit serious. Any help would be great and I can DM details.

  • Rogred76 Rog (@Rogred76) reported

    @O2 Very classy that 2 of your advisors lie and when you catch them out they hang up on you. Any potential customers AVOID AVOID AVOID AVOID AVOID AVOID JOKE COMPANY FULL OF LIES AND EXCUSES.

  • AndrewShute2 Andy S (@AndrewShute2) reported

    @giffgaff @O2 would somebody like to sort out the transmitter strength that covers PR7 before I take my custom to another network, I’ve moved to within 0.5km of one of the Uk’s busiest motorway service areas & have one bar or it drops to 3G 😡 Ridiculous & slow!! .

  • MotoGPTipster MotoGP Tipster (@MotoGPTipster) reported

    @O2 @xoJakox Same here, never won a bean and been doing it years. I’ve started to wonder the same

  • ninamduncan Nina Duncan (@ninamduncan) reported

    @O2 Did you know your 'Contact Us' page circles back onto itself so you can't actually speak to anyone! Trying to help from you guys from outside the UK is beyond annoying!

  • Rhian1975 Rhian Langham (@Rhian1975) reported

    Shocking service @O2 Your system issue cancels my order and no availability until after Xmas for a reorder. No empathy in store ... computer says no attitude.

  • FiorellaWyn Fiorella Wyn (@FiorellaWyn) reported

    Hey @O2 isnt it funny how full signal and 4g came back just long enough for @o2 to send through a message?

  • Louhawke1994 Lou Hawke ✌ (@Louhawke1994) reported

    @O2 Tried everything but its still running so slow..connection is horrendous yet I'm paying for 5G? Hmmm false advertising at its finest
