    @O2 very poor customer services fuming is an understatement 😡

  • LyndallAnn Lyndall (@LyndallAnn) reported from Hounslow, England

    @O2 This issue started a few weeks ago for me and my friend has had the same issue so changed phone companies a couple months ago.

  • Primrose_Hikwax Primmy💁🏾 (@Primrose_Hikwax) reported from Slough, England

    @O2 There was a mast down in my area but the matter wasn’t resolved for 3 weeks. I have data with EE on my ipad and the data wasn’t affected with them. With my phone I was unable to text, call or use my data. I don’t understand how you expect to put off £11, yet I haven’t been able

  • PandaEyesKirsty Kirsty Ann (@PandaEyesKirsty) reported from Maidenhead, England

    @AmazonUK I have made a large order and it has been delivered to a Amazon locker. This locker is in a private @O2 building. THIS WAS NOT STATED AT THE TIME I ORDERED! Now they're refusing me access so my daughters birthday presents are not able to be collected!!😭 HELP!

  • timlimbim Tim Cawte (@timlimbim) reported from Maidenhead, England

    Wow @O2 honestly cannot believe how poor your service was this evening. Incompetent advisor with seemingly unusable (almost useless) systems. #complaint #poorservice

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

    @O2 has GENUINELY the worst Phone line #Customerservice system ever. I've never been more infuriated just waiting to give a password or speak to someone. Please #O2 update your system to 2019 standard asap.

  • Nick_G6 N I C K 🇿🇼 (@Nick_G6) reported from Hounslow, England

    Dear @o2 and @StarlingBank it’s been two weeks and I still can’t believe that I cannot pay my phone bill via the app! Please send help I’m all out of options here. Now I’m accumulating charges for late payment 🤬🤬🤬

  • smileyyearwood Send News!☝🏾🇧🇧 #StopTheCoup 🌹 (@smileyyearwood) reported from Harrow Weald, England

    I've decided to hang onto my @HuaweiMobileUK P30 Pro until the next gen of 5g phones. Was going to take an @O2 deal but it only shows 4g and says you'll then need to take a new chip and contract for 5G not guaranteed you'll pay the same price. A lot of 1st adopters are screwed.

  • AikSaath Aik Saath (@AikSaath) reported from Slough, England

    @sabia_hussain @SEGROplc @O2 SEGRO have checked to see if the theft was on the estate itself. We'll see the young people right - just thought it might be worth reaching out to our 'bigger cousins' to see if they could help. Good to hear they didn't find anything in your car. 👍

  • boogieloo Jodie De Vere (@boogieloo) reported from Southall, England

    @O2 I love @ O2 Customer Service

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • jayblake_ Jay Blake (@jayblake_) reported from Marlow Bottom, England

    Dearest #02 @O2 I do wish all your customer service people were as helpful as the person I spoke to today. Sadly there were several trees killed in the printing of a years mobile bills, which I was told was required. Todays agent simply gave the info I needed in a 5 min call

  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • n1spm Sean Meade (@n1spm) reported from High Wycombe, England

    Following a recent mobile roaming incident (connected to a Bosnian network 4.5km+ from Dubrovnik airport), it did make me wonder why phones don’t have tiered roaming settings e.g. within EY, outside EU etc @Apple @o2 #roaming

  • johnsheppard71 John Sheppard (@johnsheppard71) reported from Chalfont Saint Peter, England

    @O2 I am an o2 customer for over 20 years ,I am not happy that I am due for an update and you cannot compete with other companies. Where is the loyalty to your customers .

  • BecOz14 Bec Osborne (@BecOz14) reported from Camberley, England

    Have had 1 bar of @O2 signal for most of this year, funnily enough when I tested the signal strength back in July the signal jumped to a MEGA 2 bars momentarily. #NoServiceHere

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

    Its amazing @O2 can sort out fraud against my 13 year old daughter but @VodafoneUK cant & tell me to go to my local shop with my daughter to prove she didnt take out a contract like wtf!

  • B_Heer84 Bari Heer (@B_Heer84) reported from Wraysbury, England

    @O2 are the biggest disgrace possible. Im a pay monthly customer, paying £53 a month. I have no network coverage. O2 have confirmed I live in a Black spot and they will not be helping me. They said to me..’These things happen’...! O2 said I still have to pay my monthly fee..!

  • daktadre Dré (@daktadre) reported from Spelthorne District, England

  • ellieradcliffe9 Ellie Radcliffe (@ellieradcliffe9) reported

    @O2 my signal has been intermittent at best, at worst completely non-existent, for the past two weeks. Apparently there's a mast close to me that isn't working (M19) - what are you doing to sort it out? It seems to be taking ages?

  • graham_105 Graham Saunders (@graham_105) reported

    Is the @O2 mobile app down at the minute ? Been trying to log in to my account since this morning

  • Danjw91 Dan (@Danjw91) reported

    @O2 Yes I get pretty slow speeds where ever I go.

  • VillaYouth Anthony Beaman 🏴󠁧󠁢󠁥󠁮󠁧󠁿 (@VillaYouth) reported

    @O2 why can I not login to update my top up details

  • GHAT69 Gerald Tomkinson 🎥 (@GHAT69) reported

    @o2 Since you have merged the service is rubbish... I have. O service and I’m working from home this is a a joke guys WHY?

  • WorcAshes Worcash (@WorcAshes) reported

    So @VodafoneUK also believe loyalty is one way - from the customer only! After more than ten years with them I am not privy to the same upgrade benefits as to someone who has a more valued handset than me! Oh well time to join @O2 who have looked after other family members!

  • Annasie1018 Anna Happiness 🥳 (@Annasie1018) reported

    @O2 last few weeks service in the co5 area has been awful, what's going on

  • IJB_XX Imogen (@IJB_XX) reported

    @O2 It’s in Stoke-on-Trent and Manchester. I have had the issues for several months now, it’s like the service gets worse and worse as time goes on.

  • boboshady Garry Potato (@boboshady) reported

    @wicksta @O2 @VodafoneUK "I'm joining O2 to get a better signal" isn't something you see every day.

  • Jimmy__Cheung MrCh00 (@Jimmy__Cheung) reported

    @EE hi. Been a long term customer but I’m swayed by @O2 cheaper tariff. Just ordered a payg sim to test the signal out 😬
