Discovery Medical Aid - Does not know there clients........ SAD!!

I have been with Discovery Medical Scheme, with Group Membership for a total of 15yrs+. In the last 5yrs+ my treatment/chronic etc has not changed with them at all. In late Feb 25, i left the company i was with. They backdated my Scheme resignation to end Jan 25 and immediately stopped all cover. I then app**** to have the Membership transferred to my personal capacity and even took a more expensive cover option. Cover was eventually incepted on 1st May 25. In this time period, underwriting had discovered a shortfall (1 claim submitted in Jan 25 - chronic etc, for which i needed to refund them R1400+ and a amount owing on a savings portion from the early 2000's when the group i was with changed schemes - R393, which had by now grown to R3800+ at there collection agent? - In the time since then, with the Group i was with, i had left and rejoined Discovery +- 3 times, never having had this amount raised as a query - suddenly it popped up on every portal of Discovery that i have - Banking / Invest etc?) None the less, the amounts were paid up to date, and my cover incepted 1/05/2025. DISCOVERY....... then informed me, that i will be subject to a 3 month (90 days) general waiting period?????????????????????????????????? They have my full med aid history, back to the early nineties, I have been loaded on their Chronic Cover listings for the last 10yrs+ and nothing has changed in my treatment, or the Chronic cover previously approved, that i will now load on my profile? First, Discovery will mention the 90days clause, then they will mention underwritings classification, then they will say " But you ticked the block to say you have current medical conditions ", all, whilst their letter of 'welcome' states that waiting periods are placed on a membership to protect the Scheme for new members, with not much medical history, who join and then submit big claims? This is not ME, you have my history, 2 months later i am wanting to submit the SAME Chronic Cover, but now i must pay you and wait 3 months under a 'General Waiting Period'? If i was a 'new member' with NO history with yourselves........ totally understandable........ but with my years & years with Discovery........... No man.......... what a shame !!
