Debiting All my money

I have been under administration for the passed 2 years, Nedbank happens to be one of the people that I owe money, in September they debited R6000 from my acc hense I'm still under administration, my money was reversed after 3 days , I was late with my other monthly payments like my rent and school fees, to my surprise yesterday another R7526.12 was debited again by Nedbank from my account, all my money Is gone and yet again I must wait for my money, this is the worst service that I have ever received and I am closing this account I want my money back TODAY....
