Life fourways hospital and life group. No respect, no proffissional staff, no mangment

Blood pressure,more than 100min Air time, losing hope this my story with life fourways and life group. My child was admitted in life fourways hospital on March 2018. I'm under international medical aid which not approved by hospital I paid 30000 for Doc and hospital in advance as they not allow my son to enter. Two day discharge then two weeks for the full invoice then I fill all information to the lady who's Givin me the invoice to refund 10000 ZAR from mid of April till today the life group and hospital play with me no feedback from life group for month or more every time I call they said system said need one doc I answer I already replay with doc then with cold voice sorry but I can't check as the lady it is not her. After 45 days calling till I have now blood pressure as every time same feedback or no answer. One time I said to the lady can you transfer to manager or customer care or complain department, number or email. She answer to say go to the hospital I said to her OK I need the address then she said sir we close now. I said no problem need address at least, sir we in Johannesburg and we close if need go to hospital any thing else to support!!! Finally I call one good lady was respect me to give me feedback the document still in the lady desk and I promise two days then will send to hospital and don't worry they taking 48hours.?!! 45 days my refund document sleep on the lady desk. How the manager for this company accept that!! Then now for week document in life fourways and when I ask them they said don't complain this not our issue this life group company was delaying now need to be patient and wait, no SLA no one no when the money will back.
