Blizzard mistreatment

I just got my account back from a hacker and he moved all my characters to a sub account and moved all their servers changed all their names races... he even changed my battle.net email and password before it was recovered.... Now blizz is telling me that its my fault to account for security during the 5 months i quit because of my illness...They refuse to restore my toons to the way they were prehack and say i have to pay it myself which would cost me 500+ dollars to change my characters back that i need to help pay for medical bills...they are saying there is no evidence of it being hacked but clearly all of the things done show that it has... how can blizz treat someone whose been playing for 6 years this way.. and now they are threatening me for harassment for making too many tickets to fight this.. if i get banned then so be it i want my story heard
