  • 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!!

  • 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

  • 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.

  • 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

  • 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

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

  • 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.

  • 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?

  • 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

  • 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

  • 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 🤬.

  • 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.

  • 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

    At @O2 is it standard practice for your staff to put the phone down on customers just because I do not want an upgrade ? @O2 #sorude #nocustomerserviceskills #o2phones

  • wnaz37 Naz Wilson (@wnaz37) reported

    @O2 Thank you! Fingers crossed you get it back soon I'd hate to leave the network.

  • johnski2000 John 🌈🇨🇾 (@johnski2000) reported

    Dear @O2 how can a talk to a real person? A phone number would a good start. Aura is incompetent and can’t help.

  • The_Caz Caz Young (@The_Caz) reported from Wandsworth, England

    @MancJules @O2 Yeah, they look like legit numbers but when you answer it's a stupid pre-recorded scam call!

  • topher_lynn Topher Lynn (@topher_lynn) reported

    @O2 Done everything & this isn’t the first time this has happened at the exact point I want to use it. Not good service if I can’t access the app and have to go through the hassle of going through a web browser. Should be pain free... not a happy customer

  • th1v_r86 Thiviya Raveendran (@th1v_r86) reported

    @O2 trying to find my PAC code so that i can switch network and you have literally made it impossible to do so! Not happy at all.

  • JaanuBhatt jaanu bhatt (@JaanuBhatt) reported

    I m in uk.. n I m using the o2 network from the 4 months.. and I want to take my another device with that... but they said always like ur credit check is declined but I checked my credit score online n it’s good .. so why it’s like that..????? I want a answer.. Plss @O2

  • tombarnard59 tom (@tombarnard59) reported

    Customer service from @O2 is appalling. Added another phone to my current contract for my son. Too cut a long story short my son still cant use his phone as the o2 shop gave me an invalid sim card. 10 days into the new contract and still unable to get service......

  • Evil__Evelyn Evelyn (@Evil__Evelyn) reported

    @O2 Is there a reason why I call again and your idiot agents have a hearing problem and I am having to repeat myself 5/6 times and having them repeat it back 5/6 times and is there a reason they have to be demeaning calling me "darling" or "lovely" or "dear" its rude

  • winter667 Chris Winter (@winter667) reported

    @O2 Trying to unlatch an old iPhone 6 from your network to give to a relative who has broken their phone. We put an 02 PAYG sim in and tried to get it unlocked and get 'the imei hasn't been used on our network with the MPN provided' - how do we get this phone unlocked??
