Incompetence beyond comprehension!!

Since on or about September 2017 I began a process to move my medical aid from my previous employer to personal and SINCE SEPTEMBER 2017, Discovery Health has still not gotten it right! During the process, I provided the debit order details and was expecting the first amount to go off at the end of September and that was not done ad found this out when I received an SMS from Discovery communicating that my family was not covered! I then got on the phone to sort this out and spent ages on the phone holding on to speak to someone more senior. Ofcourse the manager and previous consultant gave me some lame story about the request not been captured correctly. Then I had to make a manual payment and had to wait some day or two for everyone to be covered on the medical aid again. At the time I was told that the debit order had now been correctly done but again today I received the same SMS again communicating my family is not covered because the debit order was not done YET AGAIN!!! I am so fed up with the incompetence at Discovery that I wish I could terminate the whole portfolio I have with them! I can tolerate mistakes once or twice but months of just plain incompetence is unacceptable! Can someone who has the ability to carry out a request correct this? This is my final request to Discovery, otherwise I will seriously be looking at leaving this establishment.
