money disappeared out of my new nedbank account

i opened a new nedbank account with no debit orders loaded onto it as my previous account was closed due to outstanding overdraft which i could not pay as a result of losing my job. My account balance has gone from R2040.07 to R-929.93. I have no idea where this money went to as i have not given nedbank my permission to load any debit orders on this specific account.i do have a nedbank personal loan which is in arrears but i did not give nedbank personal loans the new account details.id still unemployed and cannot afford repayments as of yet.that money was for petrol, food, electricity!i want my money back!!!this is theft
