    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Any plans on enabling sms over wifi calling? I used to be with @EE and I could call and sms with wifi calling but seems your network only supports calls?

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • paul_a_lewis Paul Lewis (@paul_a_lewis) reported from Barnet, England

    @O2 my wife joined O2 today and ordered a new phone however she provided you with the wrong email address, can you help change it? Thnx

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported from Walthamstow, England

    @O2 I don’t know what I’m paying for? Unless I’m somewhere with WiFi I have the worst internet, anywhere I go! I’ve tried all the steps to fix and still terrible internet. Unacceptable!

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • monicathenurse Monica, BSN, RN, MFCI (@monicathenurse) reported from Walthamstow, England

    @O2 hi I called customer service but they can't find my account I want to give notice to cancel my contract.

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

    @O2 @ammyylp 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?

  • PhoenixThCo Phoenix Theatre Company (@PhoenixThCo) reported

    @O2 NEVER GET A PHONE WITH O2. They are incapable of communicating. Their customer service is absolutely terrible. Second time in a week they’ve cancelled my entire account. Fraud department don’t respond. Absolutely appalled.

  • Experimentness The Greater Good #StayHomeSaveLives (@Experimentness) reported

    Over a year on and @O2 still haven't fixed the mast issue in my area. Definitely changing provider at the end of my contract. Fare thee well, 13 years of custom!

  • 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.

  • ClaudineStanbu1 Claudine Stanbury (@ClaudineStanbu1) reported

    @O2 just received a call from you on my house and mobile phone. Answered both times but was disconnected both times. Do you need to speak to me if so why hang up🤔
