Discovery medical aid no afterwards assistance

Discovery has no after sales service nor customer care. We renewed our Discovery medical aid in November, up to date, we have not received our new cards. Multiple calls and numerous emails fall on deaf ears. Every time we get to a consultant, we are promised the cards are on the way. Then we get told about virtual cards, fair enough but we have requested our physical cards which we should've received months ago but never do. I hate to think what the process would be should we need something major or an authorization from an accident scene. There Is just no interest after the deal is done.
