So far as I know from previous questions like this, you would need to start a new account and you would lose your purchase history, unless you logged in with the old user name to access it. From what I've read, they can't or won't transfer history to a new account.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
