  • 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

  • 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

  • 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.

  • 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

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

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

  • 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!!

  • 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?

  • 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.

  • 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.

  • 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.

  • 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?

  • 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

  • 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!!

  • 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

  • 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 🤬.

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

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

  • 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

  • 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?

  • 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!!

  • 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

  • tweetnicc Nícolas Buitrago (@tweetnicc) reported

    @O2 Get your **** together, the website crashes right after joining the queue!

  • rokerzammo David Cain 🇬🇧🇺🇦 (@rokerzammo) reported

    @O2 Is this the same as the Peter Kay ticket fiasco ? When your site was supposed to be down but somehow all tickets got sold ? Priority ? For what ? Seems you haven’t fixed it from last time then. What’s the point in having priority if every time a big event happens, you can’t cope

  • suzid238 SD238 (@suzid238) reported

    @O2 The trouble is i was supposed to make the payment on 30th. Which i tried for over 3 hours. Now ive got a letter saying ive not paid.

  • Traciiee ǝıɔɐɹ⊥ ♡ (@Traciiee) reported

    @O2 Nah. I'm too irate at the idiocy from the O2 customer services person I just spoke to. Gave me a phone number to call, and guess what?! The number isn't recognised!!!! Excellent service! 10/10 !! 🤬

  • vannerbird ☀Ange☀️ (@vannerbird) reported

    @AppleSupport Always a good signal in the past in other areas. Patchy 3g in my village due to @O2 mast. Following latest ios16 update, iPhone 13 only on ‘Edge’ with intermittent flashes of 3g. On #ios signal search on here many are complaining about signal issues.

  • thewishy Steve Scott (@thewishy) reported

    @o2 Your website is broken, I've spent 2 hours on hold trying to call you, text chat is offline as "too busy" and DMs get a wonderful suggestion to use the broken website. How hard is a sim swap??...

  • sean_mcluckie Sean McLuckie (@sean_mcluckie) reported

    @LottieBenton_ @O2 No problem

  • richa_michael Michael Robert Richa (@richa_michael) reported

    @O2 My god you can't operate your app correctly,you can't maintain your masts correctly which means your customers don't have any service how the hell are 02 still in business 02 has become a laughing stock

  • oliviaptee Olivia Tee (@oliviaptee) reported

    I have spoken to multiple customer service advisers over the phone to get a proof of purchase for insurance purposes and every time they’ve failed to send me one. Please help! @O2

  • mradknight Andrew K (@mradknight) reported

    @O2 I’ve done all the basics, I just cannot get it to work. I left O2 a few years ago because the signal was crap, maybe I’m going to have to do it again.
