Discovery complaint

I have been waiting for an auth approval for over a month . I app**** for membership with Discovery in December 2025 and the broker who was assisting with the application was Abongile Mtengwana . Our application was approved and our join date and benefit date is the 01/01/2026. My son was operated on the 03/12/2024 for a fractured knee and he was fully recovered by the time of application. He started experiencing discomfort from the ankle mid Jan and the surgeon suggested that he needs to remove the ***** as it’s distracting the bones from growing. Discovery is refusing to authorise the auth as a Non-disclosure. The question I was asked when applying was whether there were any operations in the past year and I declared to the broker that the answer is no and I elaborated that my son’s operation was done way over a year ago , therefore the answer is no…Discovery has been investigating for over a month now and I am told that they don’t have access to listen to the call of the day of application with the broker , I don’t know why. I have been waiting for a supervisor to call me back and it’s been a week now . I was told by a discovery employee that if I do not accept the outcome ( auth declined) then they will cancel my membership…I need assistance with this urgently
