Used to work for them back when they were Orange and a colleague got apparently got hauled over the coals for popping in a celebs name into the customer record viewer out of idle curiosity. Didn't access the account, just searched the name, but it flagged it somewhere and before the day was out he'd been pulled in for a disciplinary meeting and told in no uncertain terms that had he accessed the account he'd have faced dismissal on the spot. So, for celeb accounts at least, they are on the ball.
