  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • julie_virgo1 julie virgo (@julie_virgo1) reported from Croxley Green, England

    @O2 #02priority can't seem to get a code for hairspray.. Can you help? 😲

    @O2 hi I called customer service but they can't find my account I want to give notice to cancel my contract.

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

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

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

  • 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!

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported from Walthamstow, England

    @O2 I don’t know what I’m paying for? Unless I’m somewhere with WiFi I have the worst internet, anywhere I go! I’ve tried all the steps to fix and still terrible internet. Unacceptable!

  • 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.

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • 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.

  • 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.

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Fixed the issue. Turned Volte off, rebooted, turned back on and got wifi calling back :)

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

    @simonmaroulis @O2 Best me to it. The worst signal of any network I’ve ever been on.

  • philcas38 Philip Cassell (@philcas38) reported

    @O2 Motorola DynaTAC 8000, we had 3 of them on the Vodafone network in the early 90's (The Brick) had to carry in a briefcase although they did come with spare batteries and belt holders case. New name "The Pill" because most go into depression if they separated from their phones

  • simonmaroulis SIMON MAROULIS (@simonmaroulis) reported

    @O2 Funny because you can barely use your network nearly every where I go.
