Same error here. Not had this one before.Constantly have had issues over
a decade with o2 and logging in to generate bill PDF's.Never-ending
incompetence from the system development team. Even set up a new account
and still have issues with that one ...
I'm getting the same issue. Seems so many things including reporting
this issue require you to be able to access or go via the My O2 app or
logging in. Major issue when this is the fault you're trying to report.
