Administration nightmare!!!!!!!

I have been struggling with Discovery to get a 3 month waiting period taken away for the last two weeks. I put on the application form that my husband uses a probiotic. Now they are insisting that he is using ongoing medication for a medical condition. I have phoned them to correct this. My gastroenterologist has written a letter to state that it is not chronic or ongoing use. Still they do not want to let go of it. This morning my husband told me that he isn't even drinking it anymore. Firstly a probiotic is not classified as medicine, but as a supplement. Secondly my husband has not got a medical condition. I then try and phone to get the 3 month period cancelled, but alas I am told repeatedly that he has to take medicine for an ongoing condition. Isn't that the reason why I am phoning? To correct THEIR administration fault? If they do not have the appropriate s****ed personnel to understand when something is classified as medicine or a supplement, and making decisions as important as medical cover, then whose at fault here? Most of the staff I spoke to were kind and patient, except for one, a Abongile Maleni. She was telling me that my husband needed the medication for his condition otherwise he would not make it on a daily basis and started raising her voice at me. we ended up in a screaming match. WHO ARE THESE PEOPLE???????? I have contacted Mr Gore, Broomberg and Kallner. Very very disappointing indeed!!!!! And as much as the others were patient and nice, they were not of great help. If you cannot understand that the member is phoning to inquire why there is a waiting period and you try to resolve the mystery condition and medicine that YOU AS DISCOVERY has WRONGLY specified, then I just don;t know what else there is to do but cancel the membership. I hope that someone can make some sense from this and can give me some sort of RATIONAL ANSWER and correct the mistake on YOUR side. Thank you.
