a) I don't know the password

b) the security information is wrong (which I couldn't change before linked accounts because I didn't have the password)

c) the form to reset it is rejecting my information straight off and I'm now locked out

Is there anyway I can access this account at all or is it lost forever?

NB: This is an account for a University Society, so was made by previous presidents, therefore the recovery information is hard for me to guess. I've got three subject emails where I'd previously forwarded emails on, as well as four email accounts and this isn't enough... I don't recall there being any folders for me to name
