Recently active topics in Facebook tagged with login problem

I had 2 addresses on the account so I presumed my login would default to the 2nd address, which it hasn't.

I tried to reset the password using the secondary address, which has just created a totally new profile! I have e-mailed facebook several times, but they just keep resetting the password for the new profile, which obviously doesn't help me access my original profile!

Is there any way to reinstate the original login e-mail?

Many thanks!
