Terrible service from AIG (hospital cash back policy)

It is the third time that I write a review about the terrible service of AIG. One of AIG's brokers sold a hospital cash back policy about 30 years ago to my parents. Everything was fine when they were healthy and not in hospital. My dad is 88.5 years old and in and out of hospital now. I refer to the following claims: ***ZA, ***ZA and ***ZA. First he was admitted with pneumonia. I sent a detailed hospital account, bloodtest results that indicated the specific bacteria, X-ray report that indicated that he had pneumonia, motivational letter from a specialist. Yet, it was not enough proof for AIG that it was necessary for him to be admitted to hospital. Lerato Mapaletsebe then requested daily diabetic charts. I sent the diabetic charts as well as the daily vitals, but did not receive any response. She is frustrating me for more than 3 months now. I sent everything to her and then she told the managers that there is still outstanding information. This is not true. I sent everything to her and I got proof. Loretta King is also doing exactly the same. I sent all the necessary information to her and still she is not satisfied. One of the claims was sent to a general practitioner and according to him it was not necessary for my dad to be in hospital for 10 days and he decided that only 4 days in hospital were necessary for my dads condition. He is only a general practitioner and did not even consult my dad. A professor in urology admitted my dad and kept him there for 10 days. This is really totally unacceptable. According to the wording of the policy the policyholder bears the onus to proof that admission and stay in hospital was necessary. I am really disgusted with AIG and will tell everyone about the terrible service and all the lies when they sell the policy.
