    Thank goodness all our @O2 devices have such great service here as the satellite internet people do not seem in any hurry to fix our broadband. They say an engineer might come out in "around 10 days". Why do we need an engineer for a billing mistake? They have no idea either

    @O2 just to let you know, the O2Priority app didn’t load yesterday when I was in Caffè Nero’s so I couldn’t redeem my free coffee. Other people also had the same issue.
