  • 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!

  • 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

  • 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.

  • 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

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

    @O2 simply dreadful customer experience tonight -felt really let down

  • Mattoco Matt O'Connor (@Mattoco) reported from St Albans, England

  • 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.

  • emmatrainis Emma Trainis (@emmatrainis) reported from Shenley, England

    @O2 I ordered Disney + on 24.12.20 on Priority and have not received an email. Cannot get through on phone or live chat. Please can someone help me

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

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

  • 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

  • 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

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

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

  • 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

  • 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.

  • 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?

  • 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.

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

    @O2 I have an enquiry and can’t find an answer on the ‘My O2’ page. Please help. #CustomerService #o2

  • 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.

  • 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

  • helsr46 Helen Rutherford (@helsr46) reported

    @O2 hi, the code on the 02 priority app for the Apple Music offer is not working?

  • lucky_star06 Faye (@lucky_star06) reported

    Terrible @O2 coverage at @fdarena, spent about 10 mins stuck at the door unable to connect to ticketmaster app or website to show mobile tickets to get in. Had to log into my account on my sisters phone in the end (Vodafone) 😠

  • TheWhitWoo Ryan (@TheWhitWoo) reported

    @KNMNoble @O2 I havent had signal for 3 days now! O2 does not help, the network app says I have good signal in my area but I dont trust it

  • Londonscotty Scott (@Londonscotty) reported

    @O2 being charged premium rates for texts from 87121 - no idea who they are or how to stop it! Help, please! Can you block them?

  • LauraMWhite MissC (@LauraMWhite) reported

    @O2 Thanks, I did that check and it is telling me no but unofficial websites are saying that your network is having issues, strange. Never had this happen before.

  • Furbz_85 Adam (@Furbz_85) reported

    @elizabethAVFC @O2 It's dreadful isn't it. No matter where you are it sucks. Even after doing all the O2 tips (which are common sense stuff really) it doesn't improve. How can a whole town the size of Blackpool have such bad coverage.

  • elizabethAVFC Lizzi 🦁 (@elizabethAVFC) reported

    @Furbz_85 @O2 I went last weekend- I’m on o2 also, absolutely shocking for signal! Couldn’t FaceTime my son to say goodnight, first time Iv left him over night in 18months! 😕

  • ThoNd03 ND03 THO (@ThoNd03) reported

    @O2 how come my wife and myself have exactly the same phones taken out with 02 on the same day, same packaging, she can never get a signal even now sat next to me why?

  • WeegieInWales *weegie* (@WeegieInWales) reported

    When your 5yo falls at school & they can’t get hold of you because your @O2 signal never ever works. Last straw

  • NathFerguson Nath (@NathFerguson) reported

    @pbeaton83 @mrandrewdickson @O2 I know their signal is pretty poor everywhere U go i thought three signal was bad but o2 blows 3 out the window
