Google admin login not working, cant rememebr email used to login, same old story, cant pay !!

[Administer GR]

Ok i have been through this before, a year ago i got a new credit card and received a email saying i was billed but there was a problem, i tried login into the admin account using the domain name and the password did not work, i then put my email address but it was not linked to the account at all, i finally tried login into the account via chrome which stored the credentials and that worked, i updated my credit card details and was billed.

Since this period i had to re install my OS from scratch several times forgetting to store any settings from Chrome, i had no real plans to use it and now im back to square one, i get a bill again, cant login, i try an email but its not linked, it goes into circles asking me if i want to add a google account in the login page, what can i do, i assume the email i got the copy of the bill is the same one linked to update a new password but its not the case at all.....i fallowed all the details on the edmin site but no luck at all.

any help appreciated.

Thanks
