  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • 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

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 trying to upgrade on app and main website but when I choose it crashes can anyone help

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • juliet_gough juliet gough (@juliet_gough) reported from Stevenage District, England

    @o2 can’t you tell me why your customer service is so appalling called twice after I was given this number 034480490202 answer the questions and then Bye thanks for calling

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • 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!

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • 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.

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

  • sarahcoysgabb sarah gabb (@sarahcoysgabb) reported from Broxbourne District, England

    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • Buster_comedy Buster (@Buster_comedy) reported

    @O2 Still no signal in Burnham on Sea!!! Be helpful to know what’s happening?

  • AndrewFishy1 Andrew Fishburn (@AndrewFishy1) reported

    I have a joke for you: what do you call a network that won’t accept you? @O2, because they refer you to a credit check team for no reason, you wait a week and no one gets back to you

  • OptimistAsh Offbrand Urkel (@OptimistAsh) reported

    @O2 can you please explain why it appears that I have a roaming bar on my account? I've never had this before and this is extremely inconvenient now when I'm abroad.

  • DeanMcmorrow2 Dean Mcmorrow 🏳️‍🌈🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🇪🇦 (@DeanMcmorrow2) reported

    @O2 why haven’t you released the hold on my refund yet? You said it would happen last Thursday. It’s now Tuesday!! Very very very poor service since you charged me three times for my upgrade…£861.54 you’ve withheld. I need to pay bills

  • stevenbird40 steve bird (@stevenbird40) reported

    @virginmedia @O2 is it a coincidence that now you have joined forces both your signals in the Liverpool 8 area have become terrible not getting decent home broadband and no phone signal struggling to get 1 bar if that

  • darrenj02173158 Dar ta (@darrenj02173158) reported

    @EE Tempted to leave @O2 and come to you. Sick of low signal. Especially 4g

  • smlmedlrg Shaun Laughton (@smlmedlrg) reported

    @O2 This is fascinating. However, most of the time the IVR doesn’t even work. You have no idea who I am as my number isn’t on your network, and then I end up in a 30 minute queue, and get hung up on when answered. What’s the point? Just make it easier

  • Buster_comedy Buster (@Buster_comedy) reported

    @O2 there seems to be a signal outage in Somerset,I’ve reported it but your site says there is no problem.Please have a look.👍👍

  • IamNubz Nubz 🤔 (@IamNubz) reported

    @Sam_McK_88 @O2 Didn't say it was internal staff. It's a pretty bad system that for a forgotten password asks you for the passcode that you say when you call O2. It will also send a 6 digit code. The part of this that is concerning tho, is O2s reaction to this. Hanging up and laughing.

  • philroue10 Ya Ma's Athletic ⭐️⭐️⭐️⭐️⭐️⭐️ (@philroue10) reported

    @O2 I will do if the coverage or the mast near me is still broke 15 months on I think I mite coz network is crap
