Can’t access my account and not able to recover through the automated request system

I cant access my Hotmail account and there is a lot information on it. It appears to of been either hacked or locked last weekend. and when I fill out the information to recover the account I can't supply enough info to pass security. Am i fighting a losing battle and should i give in and switch to Gmail as my primary email. Please HELP! I am a long term Hotmail user and be a shame to lose all that mail. 

Thanks.
