Poor service/ contactability , less cover than other medical aid for same price

I used to belong to a 'traditional' medical aid, but due to my husbands employer we are now with Discovery. I have just had a spinal fusion/decompression operation. Imagine my surprise when we discovered all the things that are not covered despite getting hospital authorization. Be that as it may, given all the disclaimers and restrictions to make sure you need to be hit by a truck first and admitted through ER to be fully covered, I'm still surprised by some things. For example the full back brace that was fitted in hospital and prescribed by the neurosurgeon has to come out of our day to day 'savings'. Having already paid for the MRI, tons of expensive pain medication, specialist visits, the odd GP and dentist, the saving are obliviously finished, so it all comes out of our own pockets now and we are not on a bottom end plan. I tried several times to get through to a consultant to ask if the cost of the brace had been correctly allocated to out of day to day or own savings. I eventually got through, and the consultant hung up on me. I tried many more times, I have tons of time lying down since op, and was eventually assured that it is a daily expense not related to my hospital stay, I wear the brace outside of hospital. I thought it might be a good idea to find out if Discovery has any plans where costs such as back braces post op, MRI, dental, radiology, pathology etc have extra allocation outside of day to day own savings as we need a better plan. So I logged a web request as needing a quote to join and I got a call in 5 MINUTES. I asked if the top end executive plan has any such extra cover, when the lady said NO and I said that's terrible for a top end plan, she hung up, just like that. She never even tried to tell what you do get for forking out top rates. Discovery offers comparatively less cover than my previous medical aid for the same price and you cannot get hold of them and if they don't like your query, they hang up but can phone very quickly if they want you as a new customer.
