Unable to requests actioned

Because we split or family into 2 different plans this has caused us no end of trouble with Discovery. I have the following issues: 1) Consent to manage my wife's medical aid plan. A request was emailed a week ago by our broker and nothing has happened 2) Membership cards for my wife's health plan. Cards were requested by me a month ago and what I received was someone else's cards plus another set of cards for my own plan. A week ago my medical broker also requested cards for my wife and nothing has happened. 4) Why must we apply for membership cards? This does not happen with any other company. 3) No acknowledgement of any request I make to Discovery gets sent back to me. Why is that? Every other company I phone or email sends me a reply of what I am asking for. Please can you address these issues urgently and give me a response
