Dissatisfied about my refund

I am extremely unhappy. I have been calling brooklyn day hospital's refund department. They tell me that they would reply to my emails and get back to me but they never do. To book a bed it costs about R15000 cash upfront. The patient does so, whether they have money or not. But now that R6000 is due back to me, I have to call them on a daily basis and I still get no assistance or feedback. Today the refund department were having a meeting, they took down my contact details but no one called me. So, it has come down to me having to force for my money to be paid back to me. This is unacceptable and to a degree this is ******** because patients pay in full. The right thing to do is to refund what is rightfully owed to them. This is outrageous. This definitely need to be investigated, because if this has happened to me. How many other patients have been waiting for their refunds, and to no avail. I called last week, as well as yesterday and today. No one can help me.
