Locked out of my own folder

I somehow managed to remove my own user read/write/execute rights in the chmod properties and can no longer set them back. the folder now is just a waste space and even the guy who gave me the ftp space says that he can't fix it either, he doesn't know how to.. and said something about needing shell. i don't know what that is...
when i try to change the permissions to give the user read/write/execute permissions it says "550 Could not change perms on xxxx: Permission denied"
i can't delete the folder either, what the hell... ? what kind of option is that? "click here to removed you own rights on your own folder!"

halp!

Sorry, but we can't help you.
