Online ***** on my account

In February 2015 there was ***** on my bank account. I did open a case at the ***** department for investigation. In June 2015 they did let me know that they are not going to refund me the money that was ****** from my account. They did sent me up and down to get documents for them and they did promise me every time when I did visit the bank that my account will be sorted out and that everything on my account will be the same as before the *****. They did hand my account over now to the lawyers and they did blacklist me onthe ITC. I am willing to pay the money back to them that I did use but how can they ask me to pay money back that I never did use. They let me feel if I did steel my own money. I was always a good client from Standard bank and my profile with them was always good but now they do not want to help me to solve the problem and there was evedance on the statement that the money was ****** from my account. Please help me to solve this problem as I do not know where to go with this problem.
