Enough is enough
I've stuck with Plus for the last four years, hell i've even recommended friends to them - but there is a limit to my patience. This is the first non-loss of service issue that's affected me - i was fortunate enough to be spared the loss of email - but i suspect if i stay, it won't be the last. Despite what plus say, i suspect that account details have been lost (I'm getting spam to firstname.lastname@example.org), and i'm as annoyed as annoyed as everyone else that they haven't bothered to tell me. Now they've "secured" their system (do they even know how?) to prevent access from non-UK IPs, i can't cahnge my password (i'm on holiday in the states).
It seems that Plus can't be trusted to hold their hands up when they have a breach, inform customers of their services (no i wasn't told of the new packages either, presumable because they wanted to keep the extra couple of quid a month) or correctly manage the security of what is, in comparison to BT et al, a relativly small (and presumably shrinking exponentially) number of customers.
Time to move! Plus don't deserve to be in business.
