So disappointed in Discovery Medical Scheme!! Please read!!!!

@discovery health. I am so disappointed in the poor service i received.!!! And I am just shocked out of the blue because of what just happended!!! My Story: I joined Discovery Health in June 2018 and my membership was active from 1 July 2018. Before that i was at BestMed for more than 5 years!! So when i joined Discovery there was no waiting period for me. I visited a specialist on the 17/07/18 whom said i had to go for an operation on the 14/08/18. I phoned Discovery for pre-authorisation. They had a query about something and said that there is a medical assessment form that needed to be filled in by my DR before they can consider to give Authorisation for the operation. I had to wait 8-16 working hours from the time they received the from from the DR for them to respond. Their time exceeded that in the first place- I waited for then 32 working hours for a response, but that was not a problem to me. So eventually they phoned me back with the following information. 1. They declined the authorisation for the operation!!!!! 2. And my medical aid will be suspended as in immediately!!! not really telling me why????? At that time I was at work! They told me they would send me an email to say about my suspension- up until now I haven't any email to state that my membership is not active anymore- but when i phoned the call centre they could see on the system that my membership is not active anymore. And when I phone the number i was told to phone for more information at their standards department--- there is just NO ANSWER!!!!! Have phoned over 30 times now How can one just do this????
