  • 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 why is your 4G so bloody awful at Liverpool Street Station

  • 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 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

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

  • 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 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

  • andrew_conaboy Andrew Conaboy (@andrew_conaboy) reported

    @O2 I live in Germany, today I paid off my devices, left o2-uk, was given my PUK code, closed my o2 account and inserted my German SIM. It does NOT work. Now I have a phone which I personally own and no way of using it. I need help urgently.

  • AJM100000 AJM70 (@AJM100000) reported

    @O2 where is my phone? Supposed to be delivered today. Says on dpd o2 requested it back?! Nice to be contacted! Awful company

  • ReissOmari Gordé 🦩 (@ReissOmari) reported

    Could you please check if there is a mast down in the B44 area?? No signal whatsoever for about 5 days now in the same spots. @o2

  • Chops8592 Rohan (@Chops8592) reported

    @O2 Hi, thanks the response. I’ve tried the website, and when I click on to see the offers it takes me to virgin media’s website. I click on the “I’m an o2 and VM customer” option there, then it asks me to sign into o2 so I’m trapped in the cycle of signing into both sites

  • iamduncan Duncan Mellor (@iamduncan) reported

    @O2 why is your 5g so slow in Bedford. It has never been over 22MB and for weeks now it barely gets over 2MB. I only live 500 meters from a mast

  • karenmmcmanus Karen McManus (@karenmmcmanus) reported

    @O2 I'm an O2 customer since the BT Cellnet days. I love the brand, style, priority, the perks. I have enjoyed working for O2 and Telefonica! But if I can't do something as fundamental as look at a phone before I spend £500 on it, then I guess our time really is up. 😒

  • joanna_hart08 Joanna Houghton (@joanna_hart08) reported

    @O2 Your network checker says it’s a mast issue. When will it me fixed? I’ve signed up for updates and heard nothing in two weeks?

  • sosamuk sam rose (@sosamuk) reported

    @O2 All up to date, I’ve restarted the phone and it’s with all contacts and when I went into the O2 shop they said they couldn’t help and to contact you online

  • OliverBanks Oliver Banks 🇺🇦 (@OliverBanks) reported

    @O2 I DM’d a while ago. Still no PAC, still no phone service. Can’t even ring you to chase because I literally have no phone service.

  • joanna_hart08 Joanna Houghton (@joanna_hart08) reported

    @O2 I can’t make or receive calls at my home address due to a phone mast issue. Are you guys fixing the problem? It’s been over two weeks now
