Changing a Google account's default email?

Hi

I have a Google account registered to an email for an old domain that I still have access to but is going to expire and I probably wont be renewing it as I changed my sites name and have had a new domain for a bit (kept it to redirect for a while)

I want to turn this account into a personal one as I have an account for my site, but if I add my Hotmail account my old site one still stays as the default without a way to change it. There is a form online that allows you to ask for it to be changed but every time I try to use it I get an email telling me to login to my account and click change email, which will apparently change it so that my Hotmail one can be default.

The problem is there isn't a change email just add another (but the old one still remains as default) and every time I try and use the form I get the same email back.

Anyone got any ideas? Is it just me or is Google a bit of a mess account wise.
