Monthly Double Debit and Termination of Membership

I have been a member of discovery health medical aid scheme and since 2022 I've been having issues with my medical aid; 1. My newborn daughter was excluded from my plan even though I'd submitted the forms well in advance and got confirmation her addition. 2 Every month since June 2023, I've been double debited and when the debit order isn't fulfilled, my cover is terminated each time. I've had numerous calls with discovery with promises made that these error will not reoccur, but without, each month, I get double debited. It's now resulted in me paying for medical expense in cash each time which is quite costly and a great inconvenience, I've had an emergency with my daughter that I had to pay cash for, further, I could be involved in accident and my cover would not permit me to get the medical treatment I pay for each month manually. As a result, I have escalated this with the ombudsman as internal efforts seem to fail me each month.
