    💡 check your Tesco clubcard account - vouchers for restaurants, Denby dining sets & more - I’ve enjoyed 3 course meals for 2 for like £1.13! 💡 check your topcashback account could be £££ for a M&S voucher for example 💡 If @O2 customer make sure you download free priority app

  • irishangel84 Shauna (@irishangel84) reported from Belfast, Northern Ireland

  • Gloryh24163603 Gloryh (@Gloryh24163603) reported

    @O2 why is your priority ticket sale not working.

  • Pipsypop Pip Adamson (@Pipsypop) reported

    @MsMarthaHolly @O2 Both are down 🙄

  • Rob60326930 Rob (@Rob60326930) reported

    @O2 Never used any phone provider for as long as I can remember other than O2 and about to upgrade my phone. Loyalty is repaid by having a Priority ticket facility that doesn’t work when you want it to. Loyalty is a two way thing and O2 and I are about to part company

  • sazaroo8520 Sarah Hickman (@sazaroo8520) reported

    @AshleyG72960578 @JordanKinsleyx @O2 Go straight to Peter Kay's website, bought 6 with no issue at standard price. Go go go...

  • Islatpttw OUT OF ISLA’S SYSTEM BEING PROUD OF TOM 😗 (@Islatpttw) reported

    @GillianLeslie7 @william91080 @O2 I’d give up with that and rejoin the queue. I know it sounds ridiculous but twice I’ve brought tickets on that website and I’ve been stuck on that and it never stopped I had to go onto a different device. I think it’s a glitch. These ticket apps should be more prepared 🙄

  • bony_tucker Tony Booker (@bony_tucker) reported

    @O2 It’s almost as if you don’t actually expect anyone to use a service you charge everyone for the privilege of using! Rather pay less and not have these non-priority moments

  • Hazyday21 Elaine Day (@Hazyday21) reported

    @O2 @Kellyann24007 Just crazy!! How much longer??!! Are @virginmedia having same issues?!

  • Bionic_Candy 🌸 K 🌸 (@Bionic_Candy) reported

    @becJxo @peterkay_co_uk really is, @O2 need to fix there servers its unacceptable

  • laurabazza123 Laura Barrett♥ (@laurabazza123) reported

    @O2 Still getting the 504 gateway error when trying to log in. Never been logged out of the app before so why now ? Absolute disgrace, this is not “priority”! Tickets already on Viagogo getting resold for extortionate prices ! Quick enough to take our money for a phone bill!

  • Paddy_Gibbons PaddyGibbons (@Paddy_Gibbons) reported

    @O2 could run a bath. Poor excuse of a network provider
