cant sign into hotmail!

Im having trouble signing into my origianl Hotmail account due to the fact someone has appearently hacked it or something. When i sign in it tells me Sorry someone else is using this account and redirects me to a page to recieve a code but i dont have a Bellsouth account so i clicked Dont have any of these options it redirects me to another page requesting Name of Email trying to get into then asks for Aa different email to send information to so i type those in. Now when i recieve an answer after submiting all the Info i have EVER used for that account they reply with a SORRY THIS ISNT YOUR ACCOUNT. My Secret answer thing as a mutliple answer thing to to me have multiple people i admire historicly so theres one prob but the rest of my Information i submit is as accurate as can be could use some assistance with the prob if at all possible.
