Not Paying out to doctors

I am a female international student at the University of the Wi****ersrand, I joined Compcare at the beginning of the year. When I joined I paid for the entire year. I never got prescription glasses so the 3,800 rand I paid at the beginning of the year could be said to be still functional. I got 3 prescriptions from Dr Nchabeleng at Park Lane Hospital and these 3 visits costs me 948 rand. They did not pay this Dr citing insufficient funds saying I had run out of benefits ???? I also did a blood test at Lancet and they also did not pay, citing that I had run out of benefits. Now I am facing a lawsuit for non-payment, but I dont have the money to pay these claims that Compcare wont process. I have contacted them on numerpus occassions and they are insensitive to the point of sending me a bulk message that says im out of benefits. I have contacted the International Students Office to lobby that Compcare be banned from supplying medical aid services as this is ****************. All I want is for my claims to be processed. I am now facing legal action and I cant afford this as a student. They are taking advantage of international students, and its not fair.
