    @O2 This is the 8th day without my number since I asked to port to your network - What are you doing to fix this?

  • ASoltorn Archibald R Soltorn (@ASoltorn) reported

    @EnglandRugby @O2 Be good if he picked the right 15 players for a change. Sticking with the same old players out of position, with a poor game strategy isn't working.

  • arealpageturner Lisa Gills (@arealpageturner) reported

    @O2 Amanda in business has been amazing. I've had awful problems with signal in the CR4 area. Sadly I'm leaving the network but your service has been fantastic #customerservice

  • CoombesCars Coombes Cars (@CoombesCars) reported

    @O2 having to tether my o2 phone to my 3 mobile just to get signal while I’m out. Is this acceptable ongoing service?

  • PaperGoblin WildAnnie (@PaperGoblin) reported

    @virginmedia @O2 I've emailed lutz schueler in the hope that someone might actually try and help.

  • RobVinWyatt Robbooooo Dobbbbboooooooo (@RobVinWyatt) reported

    @O2 hey o2! My 5G sucks ***…. I get full 5G but the speeds when I’m at home are lucky to get to 20mbps! When sitting in the same spot turn onto 4G and I’m getting 120mbps + 😬🙄

  • Handsintheruck1 HandsintheRuck (@Handsintheruck1) reported

    @EnglandRugby @O2 Jones' persistence with Youngs ahead of in form exciting 9s in the past (Spencer/Robson/Care) and present (Quirke/Mitchell) is farfetched. Youngs has been hanging on by a thread for years now with his slow service, inaccurate kicking and inconsistent performances.

  • heidilouwood heidi (@heidilouwood) reported

    @O2 How many per customer?

  • JoshAndjie87 Josh (@JoshAndjie87) reported

    @EnglandRugby @O2 Can the Marketing team help Eddie out and put the numbers these players play for their club next to their names so he might pick them in the right positions...just an idea

  • HigginsTayla Tayla Higgins (@HigginsTayla) reported

    @O2 could someone please help with advising on a reward claim for a new contract? Tried the app but no one is able to help at the moment
