  • 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

  • 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!

  • 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.

  • 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!

  • 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!

  • 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

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

    @O2 I love @ O2 Customer Service

  • 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 .

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

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

  • 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

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

    Is anyone else experiencing call drop outs and freezes on #iPhone11ProMax I have cleared cache and done soft reset, also had a sim swap @O2 but still having buggy experiencing overheating. I’ve checked online and have reset my network settings. Minded to pop into @Apple

  • 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 🤬🤬🤬

  • 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. 👍

  • 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

  • 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.

  • 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..!

  • 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

  • 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

  • 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.

  • eeeeebcux cocolatina (@eeeeebcux) reported

    @O2 i spoke to an advisor about upgrading. She was supposed to call me yesterday and didn’t. Do customer service reps take notes so that I can speak to someone else?

  • Flamingo_code Steph (@Flamingo_code) reported

    @O2 New pay as you go customer here. Topped up £10 but the £10 free credit offer says it's not valid when I tried to claim? I didn't receive the new sim card until Yesterday and I had to wait for my number to be ported.

  • Sarah42242355 Sarah (@Sarah42242355) reported

    @O2 Hi all! I haven't been able to use my phone for a few days now because of work being done on the local mast. Am I going to be still charged for the days that the service is down? X

  • KerrieAHughes Kerrie Hughes (@KerrieAHughes) reported

    @O2 5 phone calls to 5 different people over 3 hours trying to get a resolve to sort out a phone contract, only to be told there's nothing that can be done. Quite possibly the worst customer service I have ever come across. Appalling is an understatement @O2

  • saulhxmer SH (@saulhxmer) reported

    @O2 get someone to call me. Your automated service won’t put me through to an agent.

  • Adurrrrm Adam Kelly (@Adurrrrm) reported

    When you order a cheeky @O2 sim for your mother because it’s cheaper to call someone on the same network ;-)
