    @O2 very poor customer services fuming is an understatement 😡

  • thespacedmonkey Jonny Harris 🇬🇧 (@thespacedmonkey) reported from Ealing, England

    Unbelievably bad customer service from @O2 . I was found no service when I live in London is expected and I would not be a booster and that a booster didn’t even exist. A quick google found the booster. Also pretty rude to me. Not happy after 9 years with them to get that.

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • DenisField Denis Field (@DenisField) reported from Richmond, England

    As much as I love my @oneplus it sucks not being able to go into a store and buy accessories. Especially now that @O2 are done trading with them.

  • MabdiNur1 Mohamed Abdinur (@MabdiNur1) reported from Hammersmith, England

    @O2 I’m considering to leave after many years with you due to poor connection both voice and data. Shame once u was my no 1 choice of network.

  • 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 🤬🤬🤬

  • 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.

  • s_reynolds808 Simon 'Whippet'.. (@s_reynolds808) reported from Kingston upon Thames, England

    Trying to listen to @VirginRadioUK on phone app on train and @O2 signal cutting out .. I know some areas are black spots but 3G surely should cope 😬 frustrating getting sound bites every 5 mins

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • 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..!

  • 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

  • JosephMorrison0 Joseph Morrison (@JosephMorrison0) reported from Hammersmith, England

    @O2 Your service just like, breaks all the days of the week. And let’s not forget the famous o2 outage of 2018. But at least your branding is good, except @ThreeUK might beat that too...

  • tiggsie Sarah Ward (@tiggsie) reported from Richmond, England

    @_MiddleAgedGay_ @O2 @Ofcom I will never ever go to @O2 had a contract for a year with them and found the customer service horrendous terminated my contract and went back to @VodafoneUK, which are slightly more expensive but have great service for many years now. Hope you get it sorted soon

  • AndrewTRIrwin Andrew Irwin (@AndrewTRIrwin) reported from London Colney, England

    @EmmaShubrook @O2 Agreed. I have no signal at all

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • 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.

  • stourdave Dave (@stourdave) reported from London Colney, England

    @O2 How did this shit happen

  • 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!

  • 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.

    @O2 hi you guys hve stopped replying in the middle of a DM thread. I really need help please !

  • YouthWorkerBish Keith Bishop (@YouthWorkerBish) reported

    It was ‘kind’ of @O2 customer services to drop my call... As a telecommunications company, I’ll assume it wasn’t an accident!

  • aquaman4002 Arthur Curry (@aquaman4002) reported

    Why is Pay Monthly worse than PAYG? For Xperia L4 Pay Monthly 12 month contract is £28 per month = £336 £13 device * 12 = £156 £15 tariff * 12 = £180 5GB PAYG for 12 months is £240 (£96 cheaper) £120 device £10 PAYG * 12 months = £120 6GB No incentive to be loyal customer? @O2

  • 1NickGedge Resurrected Cricketer 🆖 💙 (@1NickGedge) reported from Leeds, England

    @O2 I didn’t upgrade to an IPhone 12 📱 for your network to be 2 bars all the time and just keep crashing my phone with no network! Sort it out please.

    @O2 Trying to pay my bill online. It won’t save my card so can’t do it. Also work let me pay on the phone. Help!

  • chrisbaete Chris Baete (@chrisbaete) reported

    @O2 I’ve had enough and given up. I’ve requested my PAC code because it shouldn’t be this hard to speak to a human who can help. I shouldn’t have left EE

  • Trickle161 Trickle16 (@Trickle161) reported

    Bewildered by @O2 1hour 20mins and 4 different people on a call to upgrade and still no further on, and I was only supporting a friend who needs support by the end their anxiety was through the roof and mine was because they had to suffer that unnecessary anxiety 😡

  • sarahs0904 Sarah C (@sarahs0904) reported

    @O2 please help. You owe me £147 for a cancelled replacement handset and I want to cancel a contract. Been on hold for ages and been chasing the £ for weeks - can’t get a straight answer
