    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • 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!

  • 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

  • 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?

  • 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

  • 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

  • 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.

  • 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

  • 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

  • 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

  • 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.

  • 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.

  • 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

  • Rich3ird Richb (@Rich3ird) reported

    @O2 No! Keep your existing phone. An upgraded device is just you falling for the hype. What will it do for you that your current phone won't? No thought not.... Ignore Apple, talking **** as usual.

  • scrumpyhead scrumpyhead (@scrumpyhead) reported

    @BristolOli @BS3Rob @O2 It’s because the 02 transmitter on the top of Safestore has broken, after the electrics flooded when the roof leaked…..

  • pointing82 Ben G (@pointing82) reported

    @SteveJoyce14 @O2 It was always poor at half time but I put that down to a surge in demand with everyone getting on their phones. Haven't been since the 19/20 season was cut short tho.

  • BS3Rob Rob #SouthBristol (@BS3Rob) reported

    Having a **** mobile provider like @O2 saved you from awful tweets like “0-2 and we were lucky to get 0”, "they've now had more shots on goal than we managed all last season" & “how have we got 3 injuries without laying a glove on them". City go down 0 2, O2 go down at City. 💩

  • BuckTaylor64 Andy Buckley-Taylor (@BuckTaylor64) reported

    @O2 why in Hykeham Road Lincoln is your signal so poor?

  • ShaneDeville86 Shane Deville (@ShaneDeville86) reported

    @GrumpyBolloxUK @SteveJoyce14 @O2 I agree, O2 was bad before at Priestfield but it now seems pretty much non existent.

  • TerryRufc Terry Adams (@TerryRufc) reported

    @O2 The speaker is broke, battery lasts about 3 hours (without) me even on it and it’s slow when playing games, it lags.

  • DavidJCrosby David Crosby 💙 (@DavidJCrosby) reported

    @ruskin147 @O2 Same at @shrewsweb - must be a combination of all the metal in the stands and too many people in a single location trying to access network?

  • AlisonKMurray Alison 💙 🇪🇺 🕷️#Maskateer #CleanEnergy (@AlisonKMurray) reported

    The other two mysteriously disappeared, I've had to contact your chat on my @O2 number as my @VodafoneUK mobile broadband is not working. I'll be hanging on until 8am in the morning if necessary.

  • mm0jxi John Innes (@mm0jxi) reported

    @ruskin147 @O2 Thousands of people all trying to connect to the cell site, not really surprising you get connection problems but the mobile companies know what the demand will be like so should be able to meet that in these high profile events
