  • 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

  • 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

  • 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

    @O2 I am trying to apply the discount I get for working at Tesco,it won’t let me use my email as used for my daughters account,help!!

  • 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.

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

  • 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

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

  • IanMaxy94 Ian Maxwell (@IanMaxy94) reported from Billericay, England

    Is transferring of SIM cards supposed to give me no service on both my old and new phone @O2??

  • 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!

  • 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

  • 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

  • HarvsTheDuck Dan Harvey (@HarvsTheDuck) reported from Rayleigh, England

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

  • 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?

  • HaleAlexander Alex Hale (@HaleAlexander) reported from London, England

    @O2 @RugbyXOfficial What a shit show the organisation is at the O2 tonight.. #nopoint

  • Andy_Aech Andy Aech (@Andy_Aech) reported

    @O2 I can’t seem to log into myo2 on your website. I need help with my contract sim please.

  • princessnas Nasreen (@princessnas) reported

    @O2 hi there- I’ve had no mobile data for the last four hours- telephone line works but no data making my life very tricky. Is there a problem ??

  • MRLUKEAROBINSO1 MR LUKE A ROBINSON (@MRLUKEAROBINSO1) reported

    @O2 not getting 5g, i havent my whole contact. i can now confirn the issue is not my phone. I believe im on an esim thats limiting my phone, and contract to 4g. Can i be repaid thebdifference from the o2 error. Its not a setting on my phone, its an o2 issue. 5g here outside!

  • CarlyxMc Carly (@CarlyxMc) reported

    @O2 so putting a spending cap on my contract now means that if I hit my cap I wouldn’t be able to dial 999 if ever needed?? Bad show o2😡 #dangerous #greedy

  • iamneilpearce Neil P (@iamneilpearce) reported

    @O2 I was wondering if you had any plans to introduce a service worthy of this century. Truly abysmal. Hardly get a service at home in London. In Bournemouth now, might as well not take the phone out.

  • scoobydrue ScoobyDrue (@scoobydrue) reported

    @O2 No issues according the website, Device has been switched off and back on but this has been a constant all week at WF11 - at home I use wifi, so can’t confirm

  • JenniferBairdd Jennifer (@JenniferBairdd) reported

    @O2 just had a pretty unpleasant conversation with one of your customer service agents. Rude 😑

  • VodafoneUK Vodafone UK (@VodafoneUK) reported

    @Aotearoafeline @O2 It's saddening to hear your feedback, this isn't the service we strive for here at Vodafone. We're here to help if you need us with any issues over social media. However, we are not able to process any new connections which means you will need to speak to them directly. Millie

  • crystal0769 cceamm (@crystal0769) reported

    @O2 your customer service team are appalling! Ive been to two stores this morning then called CS - I’ve been hung up on twice, spent 2.45hr on the phone being passed about to various teams. All I want is a replacement topping up card for my 65 yr old mum!!
