Yea, i have the same problem. Tried contacting both postini and google
and no one wants to cancel my account. I even got a tech at postini
and she tried to call them and get it cancelled for me, but it didn't
work. She said it has to be done through google message security
because that's how it was purchased.
I really expected better customer service than this. Especially now
that I'm a google apps premier customer.
