    @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!

  • ElaineHenesy1 Elaine Sheppard (@ElaineHenesy1) reported from Watford, England

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

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

  • 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.

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @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.

  • 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

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • 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.

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • 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

  • 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.

  • 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...

  • 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?

  • Statto1927 Simon Hiscocks (@Statto1927) reported

    @nsandihelp Hmmm…. Unconvinced. Never had/have any problems using hashtags or phone key presses with any other organisation. Spoke to an adviser who said a workaround is to long press hashtag key for 5 secs…..haven’t tried it yet….. @O2 - is this DTMF issue your problem?

  • gilkes_e Shinnyhead (@gilkes_e) reported

    @virginmedia @O2 @peterkay_co_uk And were you planning on informing us on anything but Twitter? i.e. actual customer interaction?

  • RickDelBello Riccardo Del Bello (@RickDelBello) reported

    @virginmedia @O2 How about providing a phone service that doesn't make you waste minutes with pointless messages to speak to a human being and having actually decent people that won't hang the phone in your face when you call for help???

  • hache900 Hache (@hache900) reported

    @O2 Hi. I just moved to you as a VM customer too. I was sold a SIM only plan by one of your chat colleagues, I activated my SIM today and seems the 50gb I was told I was going to get for £15 are now 30gb. Can you help please, otherwise this is not a good switch for me. thx

  • nickhar50418548 nick harrison (@nickhar50418548) reported

    @virginmedia @O2 I’m calling you on average every other day there’s been issues in the tw9 area since beginning of October… every time you call up there’s a pre recorded message.. customer service just talk to you like your stupid and say what can we do ?? It’s a network issue .

  • jemlover1908 Lee Jenson (@jemlover1908) reported

    @virginmedia @O2 So you sent me a small cable to connect my hub to my telephone line. The problem is that they are both installed in different rooms, thus rendering the telephone useless. How do you suppose I overcome this problem? I’m paying for something that I can’t use!

  • ToddMorris_ Todd Morris (@ToddMorris_) reported

    @O2 are a joke.. expecting me to pay around £1000 to pay off my device plans on two phones, when the signal had been horrendous on them both for the last 4 months.. sat on the phone with them for about 45 minutes, only for them to put the phone down.. 🥸🤬

  • askthedood KevyD (@askthedood) reported

    Is not an issue and affordable given we’ve been doing it for years with no issue for both @VodafoneUK and @giffgaff ! The longer this drags on the more money that goes to other networks. Plus the less chance we will all stay with @O2 as they just don’t seem interested. 2/

  • JohnGib49909576 John Gibson (@JohnGib49909576) reported

    @virginmedia @O2 Fat chance, ive been waiting for 5 months now, service desk are a joke, passed from pillar to post and there is a massive language barrier and a hugh voice quality while on the phone for 1.5 hours average. Shocking service and no commitment to service. I sighed up for an 18month

  • Jenny_McShane Jennifer McShane (@Jenny_McShane) reported

    @O2 Hi, I've tried multiple times to speak to an actual person on your Access line about disabled seating for an upcoming concert and have spent hours waiting, with no one answering the call, no matter what day or time I call. Can you help, please? I don't want to email.
