Unfair service

Good Day! I joined Discovery Medical Aid January 2020 under KeyCare Plus option, since i stared to join this plan i had to submit my medical report all the time and submit PMB Forms all the time and that process will take 2 to 3 months before they can approve or decline my application. Im now retrenched from my work and my medical aid was suspended and there was a application that was submitted last year October while my medical aid was still active when im checking with discovery they say they cant help because my medical aid its not active anymore and they cat assist me with anything. Kindly assist because i fell this is not fair at all.
