  • 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

  • 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!!

  • 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.

  • 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!!

  • 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

  • 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.

  • 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

  • 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 currently a Virgin media customer and business O2 customer. Do I qualify?

  • 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

  • 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?

  • 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

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

    @O2 Yeh you keep replying to people with this, & yet the link you sent either directs back to social media, or continues the issue of login problems... so... ?? @virginmedia @O2

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

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

  • 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 🤬.

  • 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.

  • 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.

  • 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?

  • 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!!

  • Hyacintho_Azul Canny_Lad (@Hyacintho_Azul) reported

    @O2 hi, I'm in a monthly contract. Thinking of switching to cheaper mobile service provider. What's the best way to contact and cancel my contract? Thanks! #o2

  • faulkner84 Ghost (@faulkner84) reported

    @O2 your data network is terrible. Your 4G is unreliable and your 3G network doesn’t seem to transmit data of any kind. I’m paying for a service I’m not getting and your excuses are always the same. Try taking some responsibility and fix the problems.

  • nickbowes1975 Nick Bowes (@nickbowes1975) reported

    Hi @O2 I’m at my wits end with your call centre. I’ve emailed a complaint about my bill but I’m being treated by the call centre like a piece of crap. 11 years a loyal customer of 02 and its come to this. I want a senior manager to call me asap about my complaint please

  • jen_brown_77 Jen Brown (@jen_brown_77) reported

    Really bad customer service @O2, going round in circles with your multi channel approach (web, voice rec, sms, ivr) and got put through to the wrong team, the opposite of what I needed. Throwing all channels to your customers at once is not 'omni channel', its just chaotic!

  • SamirAhmed93 SK (@SamirAhmed93) reported

    @O2 just dm'd you guys about a login issue

  • MuslimShamir Follow Poor Shamir Claimant Ali Entrapment (@MuslimShamir) reported

    @O2 @Bekhboyle Can someone contact me because I want to leave your O2 network. Thanks.

  • cinimodazotrom Dominic Mortoza (@cinimodazotrom) reported

    @O2 Hi on the 4th of July I was super excited to get my new Galaxy Flip 3 5G all seemed fine then after 2 weeks there seemed to be a slight distortion with the screen. i spoke to one of your excellent support people via the app and was supposed to obtain a call back

  • katywarburton Katy Warburton 🦖 (@katywarburton) reported

    @O2 Hi, I need to change my address online but my account has a very old contact number so I can't verify I have received the texts. Please can you help. Thanks.

  • AlanVaughan Alan Vaughan (@AlanVaughan) reported

    @O2 Not any more at this end. Only when VM went down and I guess everyone was tethering. But I had issues daily when in the IoW around Newport and Cowes. Full 4G signal but no data. Drive out of Newport and all the messages rush in. How can I report that when I have no connectivity?

  • AitchLove Hannah Love (@AitchLove) reported

    @O2 Thanks for replying. I've had a look through everything already and can't find anything. Your live chat isn't working. Could this be anything to do with the Virgin outage in Reading?
