  • 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

  • hypergriffa ms griffa (@hypergriffa) reported

  • LawTRICIA Tricia 💙 (@LawTRICIA) reported

    @virginmedia the @O2 priority tickets site down all day 😡

  • 0pelfruitz Jimbo (@0pelfruitz) reported

    Maybe @O2 should have got a specialist in communications to help them organise a presale….. clearly not something they are any good at! Talk about brand damage 👏

  • chrisma5on chris mason (@chrisma5on) reported

    You’d assume if @O2 priority had a decent amount of presale tickets and their site/app has been down all day they’d still have their pre-sale allocation to sell, but more people are now saying the pre-sales sold out, it’s an absolute shambles #O2Priority #peterkay

  • Samsy2353 David Sams (@Samsy2353) reported

    @O2 @ChrisPe99357735 lol, let us login then! 10 am it is now 14:10 still can’t get access.
