Ask the community- Forgotten password and don’t have access to other options

I have forgotten my password to my live e mail account, I've been through all the different avenues to retrieve it but because I only use this account for Facebook I've never sent a email or added contacts therefore when I filled in the questionnaire I couldn't provide enough information. My telephone number has changed so I can't receive the code to my phone and I no longer have access to to the alternative email address on the account.. Please help?

Thank you
