    @O2 I was told a number would port over in 3-4 hours. 24 hours I am still waiting. Help please!?

  • KellyMSanders kelly marie sanders (@KellyMSanders) reported from Bracknell, England

    @O2 hi I waited until the pro max was saying next day delivery to order - it says it right now so I paid my last phone off to order it and ten mins later got an out of stock email. Can you tell me how to cancel everything I just did please?

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • GeorgeGower_ George Gower (@GeorgeGower_) reported from Blackwater, England

    @O2 unable to log into my o2 online to upgrade. Password etc is correct, but it’s not loading the page on numerous devices. Is there any known issues?

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

  • aamer74 aamer habib (@aamer74) reported from Maidenhead, England

    @O2 @England My ba p2 priority codes for the cinema are not working

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 the phone has been cut twice from two separate convos. Will someone please call me back and tell me why my service has been down all day!?

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • bedefeltham Bede Feltham 💙 (@bedefeltham) reported from Esher, England

    @O2 @gbuttars I'm trying to access Statements on MyO2 account as well. Says information not available at them moment. Is this part of the fix too? 🤔🙏 Please message here if so and once fixed....thx

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • UAppearance Dreaded (@UAppearance) reported

    @O2 Hi why is the reception so bad UK wide, especially in the East Midlands, from Nottingham as a whole to Kegworth. Can’t someone look into this? 21st century technology and your 4G is poor. Spoken to o2 already still no improvement

  • MartinLeaPhoto Martin Lea Photography (@MartinLeaPhoto) reported

    @O2 I still can hear the caller but often cannot be heard by them. When I first called o2 support they ran a check on my device and told me there wasnt an issue with it .....but if I have the same problem with different SIM's and if I employ my Sherlock Holmes internal .... 1/

  • BELIEVETHEREIS 𝕄𝕒𝕩𝕚𝕞𝕚𝕝𝕝𝕚𝕒𝕟. Politcally unaffiliated. (@BELIEVETHEREIS) reported

    @O2 I bought a Sim that had the 18gb promotion on it. On the packaging it read that 'as a new customer your ppromo will be applied automatically'. Mine has not. It still shows 6 gb on the website and on the phone app. How do i get this sorted please?

  • jamiecakacaz Jamie callaghan (@jamiecakacaz) reported

    Opportunity to upgrade with @O2 so I went in store the other day . Sales person trying to ram an iphone 11 pro and a "free watch " down my throat for the same as I'm paying now. Just found the deal online and it seems the watch is actually £15p/m
