    @O2 Ah ok thank you. I’ve realised that my free trial with Calm has expired - how can I find out how much this is meant to cost? I’ve been charged twice and was not reminded that it would charge me this month please help

  • KevinWNewman Kevin Newman (@KevinWNewman) reported from London, England

    @ianvisits Pointless arguing against the machine 🤖! Take your business elsewhere Ian. I’m sure @EE or @O2 will be willing to help out!

  • Munden87 AA Ron 🖤 (@Munden87) reported from Addington, England

    Anyone else’s data slow AF on @O2 constantly having issues with my data speed! It’s driving me insane! Constantly not working in places but full signal!

  • allyc375 Alison Cameron🐟 (@allyc375) reported from Kensington, England

    @O2 I have serious health issues hence a working phone is essential. Hope I get well enough to go in to your Kensington branch & sort out this weird problem. TY

  • Mr_ISC Pasha (@Mr_ISC) reported from Wandsworth, England

    Serious network issues with @O2 - calls not connecting or dropping after 30secs all morning!!

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • VictorJ1987 Vìncere. (@VictorJ1987) reported from Brentford, England

    Thanks @VodafoneUK for the run of 3 poor months of customer service requiring us to request for cancellation. Typical that your retention team could not even be bothered to make an effort. Go and listen to the phone call. I guess @EE or @O2 here I come. #Vodafone #Dontbother

  • Brunts1980 Nickle Arse (@Brunts1980) reported from Camberwell, England

    Thought @ThreeUK were bad but @o2 may have to be even worse...

  • Claudiasabram Claudia Simms Abram (@Claudiasabram) reported from Islington, England

    @O2 is your website down? I can not access my 02 to check an expensive bill nor via a link in a text

  • fbateallthepies Dowsey 🏆 CHAMP19NS 🏆 (@fbateallthepies) reported from Camberwell, England

    @O2 is there a problem with your systems taking payments .. I’ve spoke to my bank and I have no issues with my card .. but it keeps getting declined your end .. help ASAP please

  • RoseHinds Rose Hinds (@RoseHinds) reported from Kensington, England

    @O2 hi I’ve been charged extra this month for my phone / Apple Watch bill. Please could someone help me and explain why / resolve the issue

  • LebbyE Lebby Eyres (@LebbyE) reported from Islington, England

    You can tell how a company values its customers by their customer service. 2.5 hrs for @O2 to tell me for some reason I need to call the fraud dept to pay off and upgrade my son’s phone. Cut off four times yet they answer to “business customers” immediately

  • LebbyE Lebby Eyres (@LebbyE) reported from Islington, England

    Essentially @o2 treat everyone who wants to buy a phone under £200 outright like a potential fraudster. You can’t pay it off in store and they force you into a temp contract. Then make you wait hours on the phone and go via their fraud dept. Why? I’d love to know.

  • markh4780 Mark Harris (@markh4780) reported from Kensington, England

    @O2 looks like it’s gone down in London!!!! Any update on this would be helpful 🤷🏽

  • NeedMoreTea Robert Valentine (@NeedMoreTea) reported from Kensington, England

    @O2 I get masts break down etc, but two weeks is quite a long time.

  • Zenwork21 Zenwork (@Zenwork21) reported from Poplar, England

    @O2 simply unbelievable your tech and security department are not really good stop these damn scam calls #o2

  • sladey66 It’s only curly at the front (@sladey66) reported from Camberwell, England

    Is anybody else getting no service from o2? It’s been woeful for weeks @O2

  • Si11y3gg Pawlie (@Si11y3gg) reported from Richmond, England

    @VixSeaman @EE @O2 I’m with o2 also! Was with Three before, but would never bother with EE. I will only do sim only.

  • Katie_Lewis_ 𝕂𝕒𝕥𝕚𝕖 (@Katie_Lewis_) reported from Kingston upon Thames, England

    @TweetFlicker @O2 I know, o2 used to always be the best now its gone down hill fast! Sky mobile is brilliant, my daughter is on it and you get good rewards with it like o2 moments, but better!

  • allyc375 Alison Cameron🐟 (@allyc375) reported from Kensington, England

    @ShieldingG @O2 Now there’s an idea. I wonder where the cleaners put it. I’ve only ever used it for my Dalek thing - never plunged a sink in my life.

  • rogercdavies Roger Davies (@rogercdavies) reported

    @O2 Hey I’m travelling in Italy using my o2 phone. I get data up and down through your partner TIM and their network, but TIM won’t allow voice calls to UK. what’s going on?

  • kinscomp Kins (@kinscomp) reported

    Hi @O2 I’ve been charged £42.92 for 22mb of data usage in Turkey. At no point did I travel to Turkey. I’ve contacted support and have been advised it would have been accidental roaming and I should have checked before I travelled.

  • shirleyannemcm Shirley-Anne McMillan (@shirleyannemcm) reported

    Just in case anyone's trying to phone me- my SIM has been inexplicably not working for a few days. Waiting for @O2 to make it work again...

  • stavrosRN Lex (@stavrosRN) reported

    @O2 Hi, I have issues throughout the UK. Usually have a full 4G connection with a little exclamation point over my signal graphic. Absolutely zero issues outside of the UK though. As you can see from my initial tweet, I was on a mountain side with a full 4G signal with no issues.

  • Hayley_M_jones Hayley hughes (@Hayley_M_jones) reported

    @O2 seriously need to sort your service out. Pay a fortune and nebr works says I have 4g when I clearly don't not like I'm in the middle of nowhere been with you 20+ years 4 phones looks like I'll be looking to someone who can provide what I actually pay for no 4g never mind 5g

  • usukgoose Ian Brown - New Town Independent. (@usukgoose) reported

    11 days ago a technical issue affected my @o2 accounts. I've made 5 hours worth of calls. Been referred to IT 5 times. Been requesting a manager call back 5 times. And nothing ever happens. No callbacks. No IT sorting it. I use this phone to work....

  • stavrosRN Lex (@stavrosRN) reported

    @O2 The mountain side being in North Africa. Greece, Dublin, Spain and France earlier this year, no connection issues at all. Each time I return to the UK guaranteed full 4/5G with an exclamation point

  • Mel_Gillen22 Melissa Gillen - Wellbeing Coach (@Mel_Gillen22) reported from Glasgow, Scotland

    @lannygillen @O2 @O2 disgraceful customer service

  • evieannaleise 𝖊𝖛𝖎𝖊 𝖆𝖓𝖓𝖆𝖑𝖊𝖎𝖘𝖊 (@evieannaleise) reported

    @O2 my dad has no data network on his phone and because myself or my dad aren’t the account holders (my mum is) no one will speak to us or help sort this out. He’s currently travelling in Germany and has no access to his phone! Spoke to Apple and it’s a network issue! Help!

  • grrooves Grrooves💚 (@grrooves) reported

    Cancelled contract with @O2 as service so poor. Was promised to not be charged penalty for leaving early. £56 taken from my account this morning anyway. Terrible company.
