Very dissappointed

My account was hacked on the 18the of December. Since then I have been struggling to get my money back. I don't get feedback on my case, and they just ignore me. I phoned the ***** department yesterday again, and according to them my case is closed. I was so shocked, according to me, this problem is not resolved. I started banking by Absa because I thought this bank was much better than all the other banks. I was pleased with all their services, until this happened. All I want is for this to be resolved and i want my money back.
