The unfairness & rigid attiof Bonitas Medical Aid

In Jan 2015 I took the Standard Option Med Aid with Bonitas. I p[aid R3900 every month & was told that I had a waiting period of 3 months & this would expire on 1 April. I declared that I was Hypertensive & Diabetic & was told that I had to wait a year to claim on thes 2 diseases which I was happy about. 2 weeks before my deadline of 1 April, I had a problem with my eyes & was diagnosed with Graves disease (Overactive thyroid). This overaction of the thyroid began affecting my eyes causing blindness. The Endocrinologist contacted Bonitas saying that I was a Medical emergency & needed to be hospitalised urgently or I would go blind. Bonitas refused to pay & I had to borrow money to pay the hospital bill. I was hospitalised 3 times & had to pay this on my own. I feel this was grossly unfair of Bonitas not to consider a Medical Emergecy & waiver the 2 weeks until the dealine. Whats worse is that they have added the Hyper Thyroidism onto the list of \declared"diseases & this was without my permission. I had stated my Diabetes & Hypertensin as pre existing diseases. The HyperThyroidism was not listed when I filled out the forms in January. Every month I pay Bonitas R3900 religiously."""
