Worst Customer Care Service ever received

I've been trying to get a simple matter resolved since April 2021. I've called Discovery Health no less than 7 times regarding this matter. Some consultants say they can see what the problem is and will send my "Scheme Approved" claims to be reprocessed. Others are just clueless. And some just drop the call, never to call me back. Come on guys, what is going here? The year is almost finished, and nothing has been resolved. I need to be admitted for urgent surgery, but can't before you resolve your past mistakes. I've never received such Disgusting Customer Care Service before. Please have Management contact me ASAP.
