@O2 how can you have such a fundamentally broken system? Can't sign in on my browser (have cleared cache etc.) can't sign in on the app. Surely you have highly paid engineers that should stop this from happening? The incompetence is shocking.

@willyepp @O2 Don't fall for these fake responses @willyepp They are not O2! I have also found @O2 to be utterly appalling this last week, still awaiting a full refund for money they took from my account after totally messing up a simple order.

@kbushnell1975 @O2 They incorrectly registered a default on my credit file and said it will take 60 days to sort! Absolute shambles!

@willyepp @O2 @O2 have become arguably the worst company I've ever had to deal with. They messed up am order for me, then still took the money from my account. Nearly a week ago, amd still haven't been refunded.
