  • 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?

    @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

    @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

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @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

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • 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

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

  • 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

  • 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.

  • mattd1981 Matt Dickinson (@mattd1981) reported

    @O2 what the hell is going on? On the @c2c_Rail train have full 5G signal yet can’t stream a song on Apple Music without it buffering. This really is a basic requirement now and you can’t do it….. by far the worst network in the UK.

  • Winter_Phoenix8 Emma-Jayne (@Winter_Phoenix8) reported

    And it IS 100% @O2 "signal issues" because the last raid day? I couldn't even LOAD the game, I had to piggyback off someone else's hotspot just so I could participate in #lapras raid day. I'm *really* angry

  • Shaz_Kingervi Shaz (@Shaz_Kingervi) reported

    @O2 Helloooo, is the o2 network down? I can’t make any calls from my mobile 😢

  • Hobbitronicfunk Hutchinson (@Hobbitronicfunk) reported

    @O2 Xbox Series X and Samsung Galaxy Watch in this case, very odd. Not a massive issue but would explain things if youre experiencing a high payment default rate on these items if people dont pay by Direct Debit and prefer to do manual card payments

  • BarryTuckwood Barry Tuckwood (@BarryTuckwood) reported

    @O2 is the network working No signal since about 3.45.

  • loutop72 Lou (@loutop72) reported
