Netcare does not care to respond to complaints

My husband was hospitalised as an emergency. Due to his high sugar levels, he had to stay in hospital for a week while they were trying to get his sugar down. Guess what, it only went down after I complained to the 2nd in charge on the weekend, as they kept on giving him wrong food!!! He was on a strict diabetic low cholesterol diet, but was getting everything accept for that, ordered from a \diabetic\" menu!!! I sent a mailed complaint to both Netcare head office as well as the Richards Bay hospital, yet more than a week later no one has even acknowledged my complaint accept for the medical aid!!! Hospital staff that was supposed to have received the complaint, has not yet received it. Do we pay private hospitals to kill sick people with their food??? Is someone ever going to do something about Netcare's *********** kitchen, or do a couple of patients with special diets first need to die before they want to wake up and do something about the situation???"
