I am having this exact same issue. I had an account with my email address, which I closed.
I've now created a new account (using the same email address), and I can't see my current package details. If I log in with that account, I see my old (disconnected) account. If I try to sign up with a separate email address, and put my new account details in, it tells me I already have an account (with the *old* email address).
How can I fix this is?
Thanks!
