    @techdotintel @virginmedia @O2 I'm currently a Virgin media customer and business O2 customer. Do I qualify?

    @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!!

  • hadhamlane Andy Lane (@hadhamlane) reported from Bishop's Stortford, England

    @O2 ...and then when you’re signed up they change your deal to make you worse off. #O2 reducing the friends & family discount for a loyal customer is the last straw for me.. #O2

  • 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

  • MissClaireW CLAIRE WALMSLEY (@MissClaireW) reported from Halstead, England

    @O2 any resolution to your app not working, logins just go back to the same email verification page? So many people posting & no answers?

  • j4cobwood Jacob Wood (@j4cobwood) reported from Harlow, England

    @O2 I need support with my network, I’ve tried everything that the website says, my calls won’t connect and when they do the sound is cracking and poor. Most of people trying to call me can never get through either. This has been happening for months now

  • SimonHemmingshj Simon Hemmings (@SimonHemmingshj) reported from Chelmsford, England

    @O2 @GarethTurpin I appreciate your personal message. However, I now remember why I left you last time, lower than average service, and now a 17.3% total price increase, which is disproportionate and completely knobbish if you ask me. @BBCNews

  • chris_rugs Chris Ruggles (@chris_rugs) reported from Great Yeldham, England

    Hi @O2, just a heads up...me and thousands of others will leave your network if you advertise on GB news. Have a long hard think about what you will be funding. #DontFundGBNews

  • paulhayward200 Paul (@paulhayward200) reported from Wendens Ambo, England

    @O2 Took out a new IPhone contract back in November. No problems paying but I wanted to add a Apple Watch on the account. O2 keep on cancelling the order even though I pass the credit check.

  • jill_jtc Jill T food safety (@jill_jtc) reported from Sawbridgeworth, England

    @O2 Sounds easy doesn’t it!! Every call is from a different number, it wears me down, in excess of 20 yesterday all blocked & inadvertently called a couple back in error trying to block late at night with brain fog. So cross!!

  • Uptowndiscos Uptown entertainment discos (@Uptowndiscos) reported from Harlow, England

    @techdotintel @virginmedia @O2 I'm a virgin HOME customer and an O2 business customer but I don't qualify

  • JamesSharp87 James Sharp (@JamesSharp87) reported from Witham, England

    Hello @O2 I’ve accidental damage to the rear of my iPhone 11 Pro Max. Only had the phone 3 months so will it be covered under warranty?

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Great Leighs, England

    @O2 The fact it’s in 3 seperate locations, where my current projects are located, suggests it’s on your side. To use the excuse that there is too much traffic is also ridiculous as means you have over sold your network.

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

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

  • 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.

  • jill_jtc Jill T food safety (@jill_jtc) reported from Sawbridgeworth, England

    @GlassBeadsLotti @O2 Thanks - trouble is it’s not a fault with the phone; service providers have got to up theirs game to stop this happening!!

  • Uptowndiscos Uptown entertainment discos (@Uptowndiscos) reported from Harlow, England

    @O2 the answer to that question is primarily no. I would have to leave Virgin as a HOME customer and then sign up as a business customer? What about my TV package?

  • leon_dave_smith Leon Smith🇬🇧🇪🇺❄️ (@leon_dave_smith) reported from Harlow, England

    @tescomobile @O2 any coverage issues in CM20, been terrible yesterday and today, signal 4G keeps dropping out

  • JulianLittle4Ag Julian Little (@JulianLittle4Ag) reported from Little Dunmow, England

    Apologies to anyone who has tried to call me at the back end of this week. Badly let down by the useless service @O2 who are now saying that it will take ANOTHER 3 working days to move my number 🤬.

  • LongshanksE10 Richard Astley (@LongshanksE10) reported from Bishop's Stortford, England

    @o2 I ,along with seemingly many others, wish to know why your 4G has been virtually useless over the last week or so please, or better yet, when the service will improve, but you don’t seem to be replying to anyone. Please help.

  • unCAPTCHA Thomas (@unCAPTCHA) reported

    @O2 I have a device that is locked to you and I need to get it unlocked to use on a different network how do I do this?

  • WAYS____ ^ (@WAYS____) reported

    @chillmj_ @O2 terrible! & their excuse is “the network is busy in that area” okay so run me back some bread then kmt ahhhh if it’s past the 30 days mark, ride it out, after that, they’re FINISHED!

  • millie79 Lindsay Millward (@millie79) reported

    @O2 Hi, Does requesting my PAC code and giving it over to my new provider cancel with you or do I need to do anything else?

  • WAYS____ ^ (@WAYS____) reported

    I’m 100% leaving @O2 once my contract is over, they’ve fallen off so badly when it comes to signal & they aren’t as helpful as they used to be, it’s a shame!

  • Dave_Clarke_ Dave Clarke (@Dave_Clarke_) reported

    @O2 i cant seem to get a data connection for my iPad yet i have full signal. I haven’t changed any settings on my iPad. Please could you look into this as I am unable to get support via your app #networkissues

  • _aimeewillisx 𝔸𝕚𝕞𝕖𝕖 (@_aimeewillisx) reported

    @O2 is payment processing down? I’ve tried to pay my bill with two different cards money in both accounts but o2 won’t process it, but yet took my direct debit out for my device payment but I can’t pay my airtime???🥴

  • georgesbaker George Stephenson (@georgesbaker) reported

    @O2 how do I speak to a human advisor and not this stupid robot that’s the most unhelpful thing

  • chriis1993 Chris Cox (@chriis1993) reported
