    @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!

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

    @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.

  • 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

  • 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?

  • 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.

  • 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

  • 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!

    @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

  • 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.

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • 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...

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

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

  • 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

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • Cinderella_D Darren Devers (@Cinderella_D) reported

    @O2 very disappointed that I’m being advised your store in a shopping centre only has the capacity to help one customer at a time sending other customers on there way for something as simple as a sim swap. Can a store operate with one person doing work.

  • CageyManchester KS (@CageyManchester) reported

    @O2 I want to change the bank details my direct debit comes out of, I've spent the last 45 minutes trying to find where I can do this online, help!?

  • ChrisEden83 Chris Eden (@ChrisEden83) reported

    @O2 increasing my mobile bill by 12% per month…FFS! The rich get richer and the poor get poorer! The country is screwed

  • ErnestJ98572537 Ernest Jackson (@ErnestJ98572537) reported

    @O2 8/12/2019 Deborah Clark, Executive Resolution Specialist, you are withholding the sum of £970, not your money. This is as Ofcom agrees illegal amount taken you had iPhone 11 back 5 days later no refund on card, then you proceeded to take 8/12/2019 £770 then £ 37.50- £16-50-£

  • microphonemayne Ed Mayne (@microphonemayne) reported

    @mvyner48 @EnglandRugby @O2 The present isn't either. Not sure they realise how stupid they look.

  • kwr66 🐘KevR 🍒 (@kwr66) reported

    @O2 your customer service is appalling. Best part of one hour and thirty minutes I’ve been on the phone to them. 7 different representatives. Simple task of moving a number from another provider to O2. Why bother, procedure bound, inane, incoherent and the flexibility of concrete

  • JackHumphreyKM Jack humphrey (@JackHumphreyKM) reported

    @O2 do you have service issues?

  • Love_SE4 @Love_SE4💙 (@Love_SE4) reported

    @O2 Your the scammers. I was miss sold a two year contract last month. With the promise of a new phone after three bill payments. I spent an hour on live chat last night trying to get answers. I want to cancel this scam but so far no luck. You should be ashamed at the way you con us

  • davemh72 davemh #🇺🇦 (@davemh72) reported

    @O2 Credit where it’s due that’s a good thing but it’s a Shame I’ve had a poor signal in several places , hit with a 12% hike and told by customer services like it or lump it .

  • ke11ymillen Kelly (@ke11ymillen) reported

    @O2 Still don't get why it needs to go up by nearly 4% every year like regardless. Have the people not suffered enough? 😒 Tbh at this stage, I am out of contract, still waiting on the #S22 I preordered in Feb and fed up, think I will just cancel and move to a diff operator
