However, they were not content with this information - they wanted my full address and birthday, for 'security' reasons. Again, I remind you everyone who wants to send them a simple email message must go through this, plus I had logged into the site, that should be security enough.
UPDATE: The response to my message was both prompt and comprehensive, explaining that to access my bills online I needed a new login and password, one of which was in the email and the other sent to my mobile as a text message. Can't help thinking, however:
1 why did my original registration for the site not include access to all aspects of it? and ..
2 when I tried to access the bills page why not show me a message telling me what was going on?
So ... full marks to the 'problems' people - but in pure business terms, I would be looking to make you redundant by better website management - sorry.
