Help me get my hotmail account unlocked!

My  email account klcv@msn was locked. Microsoft On line safety team thinks that someone just kept typing her email address in error. May have had a very close email. If I have answered all the security questions and nothing seems wrong then why not give me my account back? I've had this emaila address since 1998. I cannot lose all my email because someone at microsoft is just being unrealistic. Not giving my account back has caused me to have to use my husbands email as the contact email and to use my Comcast account,. To date I have not received a valid reason to keep this account locked.
