  • 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 .

  • ItsMeEllisxD Ellis Brown (@ItsMeEllisxD) reported from London Colney, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • DamianPDavis Damian Davis (@DamianPDavis) reported from Spelthorne District, England

    @paddyguy51 @Ker_Anderson @Phonemast Do your self a favour and swap to a network that actually works, i.e. anyone but @O2

  • jackaarondavies Jack Aaron Davies (@jackaarondavies) reported from Richmond, England

    @O2 Not everywhere, but your 4G coverage in SW London is poor. I haven’t had 4G in Raynes Park since I moved there a year ago.

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

    @O2 I love @ O2 Customer Service

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • 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

  • 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

  • NeilNutbeam Neil Nutbeam (@NeilNutbeam) reported from Hillingdon, England

    @O2 why is the network and 4g soooooo bad. Well I say 4g, I never get 4g most of the time. And even if it does say 4g it’s rubbish and slow, stuff still doesn’t load. A lot of the time I have to turn 4g off and change it to 3G for it to work. Rubbish

  • 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. 👍

  • LeeButterley utterlee (@LeeButterley) reported from Brentford, England

    @wheresnicktoday @elgobsucram @thisisryanon @O2 @EE When I lived in Manchester the O2 4G was so bad I had to switch to EE.

  • 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

  • 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

  • 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!

  • depeare Steve Depeare (@depeare) reported from Ealing, England

    @O2 after 3 hours of calls 5 texts and 1:5 hours of to get family discount that is advertised and to be given an amount to pay then still getting it wrong . So a complaint to be made

  • Elissa524 Elissa Da Costa (@Elissa524) reported from St Albans, England

    @O2 Not sure what happened but all ok now thanks. Very good service to get me reconnected quickly

  • NasiraKasmani Nasira (@NasiraKasmani) reported from Maidenhead, England

    @O2 unbelievable service from the #CustomerService agent today, so rude lady called Ambreen kept speaking over me. Unacceptable that staff have the audacity to speak to customers in such a manner and instead of resolving an issue escalate it to another level. Who do I complain to

    @O2 absolutely furious at the ongoing issues I have with O2! struggling to get data around my work place with apps not loading and not being able to access my camera at home! Contacted an agent through the app who are absolutely clueless and unhelpful! & i now have no service😡

  • lifeofbry Bryan Scott (@lifeofbry) reported

    @virginmedia 9pm tonight. That’s two whole working days. What’s your compensation policy? I’m also an @O2 customer - can you give me extra data for tethering given you’re now merged?

  • tasha_thomas19 Natasha Thomas (@tasha_thomas19) reported

    My current iPhone is broken, I’m eligible for a better phone with cheaper bills and guaranteed next day delivery before midnight and the @O2 @TheO2 website goes down. Smashing start to the weekend 😡😔

  • egino egino (@egino) reported

    I’ve been with @O2 for years, they recently increased my monthly contact with no additional benefits and when I decided to move to @giffgaff, they charged me for cancelling the contract with them. Such a great way to treat your (no more) loyal customers #O2 #customerexperience

  • boboshady Garry Potato (@boboshady) reported

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

  • Garethwhyatt Gareth (@Garethwhyatt) reported

    Hey @O2 I've got no service at all - apparently an issue with a mast close to me but can expect an update by 9th August - nearly a month away. So what am I supposed to do until then?

  • Mrs_Stav Anna Stavrinides (@Mrs_Stav) reported

    @O2 unimpressed with customer care. Helping 80yr old sort a new phone +move number across +STILL no luck 1 week later!!! Spoken to 4 diff advisors all saying yep should be 4 hrs, still not working. Email came last night - sorry we put it in the wrong queue. #notahappycustomer

  • la_crip la_crip (@la_crip) reported

    Hello @O2 Been with you 20 plus years. Just had a message telling me I’ve just sent my first MMS message which I didn’t, plus I’m going to be charged for sending that non existent message. WTF? Should I seek a new provider?
