  • ZeeHabib1 Zashan (@ZeeHabib1) reported

    @O2 you said everyone should be connected at Xmas, I’ve had no service since Friday. I requested a 5G sim for my new phone and explicitly said I’ll activate it once I get it, as I’m currently using my older phone. Still haven’t received my new sim and no service since Friday.

    @SarahRowleyXO @O2 So I've just been told that these are on a first come first serve basis. If I cancel now, and do store pick up I might get it earlier but no guarantee. What an absolute shower of shite

  • charlll18x Charlotte (@charlll18x) reported

    @wolvesbradders @wwfcrhys @O2 Even when it says I have 4 or 5g it never works, only place I actually get any signal is at home when I don’t need it. Yeah their priority is good tbf probably only reason a lot stay with them I’d say

  • shoegal1927 AJ (@shoegal1927) reported

    @matt_saunders_ @tescomobile @O2 I feel so badly let down. To not even have a time scale is shocking. I've wasted hours and hours of my time trying to get this sorted and no one seems remotely interested. I'm so fed up.
